Right so.. I've had this happen 3 times since last night, it always happens at the same location. I load my save, I kill some Thalmor, loot them, go to Riverwood, open Sven's (my follower) inventory to take out stuff he was carrying for me, then I give him my 100 iron arrows. As soon as I have selected 100 iron arrows and press give/accept or whatever the button says, the game instantly crashes to desktop.

This is what happens every time, and at the same location. I tried making it happen again on purpose after the second time, but then it didn't happen, so I figured "oh well, I'll reload and play again normally then" aaand then in happened a third time, same location, same thing.

I looked through my papyrus log, and I can't make much sense of it, but I'll paste it here along with a list of mods I use and hopefully someone can help me because this is getting annoying.

Plugins/ESMs/Mods I use:

Papyrus Log:

Something I do not understand, is why the papyrus complains about the absence of ESP files/mods I've never even used/heard of. Like CompanionValfar.esp, CompanionArissa.esp, HothFollower.esp.. basicly any esp listed here in this log, that is not in my list, are esp's I've never used, so why is the game complaining about them?

There also seem to be some mention of Convenient Horses.. not sure what that's about, but could be the game is whining since I'm using a horse mod, but I don't have a horse yet?

And there's also some mention of the spells added by Mighty Magick.. no idea if these problems are caused by the mod itself or what it is..

Anyway, any help/tips would be appreciated.

Have you installed the unofficial skyrim patch ????

I can't see that in your load order. That should fix your arrow problems. (btw after installing wait for 31 days, and then proceed with any arrow transactions)

-------------------------------

as for your papyrus errors you should try that:

Use this with SKSE, install, go to skyrim>data>SKSE and create "SKSE.ini" and type:

[General]
ClearInvalidRegistrations=1

Save and close.

It will now clean invalid scripts from mods you don't use anymore from your save game. It will take a while and only works as you play.

Play that way for a while, and see how the game behaves !!!!

Oh right, yeah I use the unofficial skyrim patch, I didn't find any list of my currently used mods to copy paste from so I wrote them all manually, and I seem to have forgotten to write that one. Will update the list. Also I installed the unofficial skyrim patch -before- I started my save, do I still need to wait 31 days? (and are you sure you mean days? Isn't it hours?)

Also you said the clear invalid registrations thing will clear scripts from mods I don't use anymore, but those mods in that log, I haven't used them AT ALL, EVER. So why are they in the logs? D: And there seem to be some Mighty Magick related errors too, any idea if they're harmful?

EDIT: Also there's no folder called "SKSE" inside the data folder. I even tried re-installing SKSE and the only folder it adds to my data folder is a ""Scripts" folder. And I noticed that in Data > Scripts > Source I have folders with scrips for Dragonborn and Hearthfire, but I don't even own these DLCs... should I delete them?

Have you used BOSS to sort your mods into the correct load order?

Yes, I have.

Have you tried without any mods activated on a clean save (as simply disabling mods on an existing save can cause more problems)? You may want to do a trial and error to find which mod is causing the conflict.

Well, considering all my current mods were installed before I started my current save (except Mighty Magick and UFO, to do the fail-safe installs), it should be pretty clean, no? So, I don't really have any saves that are un-modded.

I mean 24 hours=1 day, so you do that 31 times. (But time goes fast on skyrim anyway)

I mean on the wait screen: for 24 hours you will wait 25 sec.

---------------------------

As you say you used mod's and then you have propably disabled those, or even unistalled (so deleted), and therefore you get those messages.

But there is a line in your log file it says: ERRORS RELATED TO MISSING FILES SHOULD BE IGNORED!

I have those errors too:

warning: Property HircinesRingPower on script companionshousekeepingscript attached to C00 (0004B2D9) cannot be initialized because the script no longer contains that property

warning: Property pTG05KarliahInvisibilitySpell on script QF_TG05_00021551 attached to TG05 (00021551) cannot be initialized because the script no longer contains that property

but guess what, my gameplay is error free from day one, until today. (I started for a couple of months)

> And there seem to be some Mighty Magick related errors too, any idea if they're harmful? <

Those should be mode related. (You actually use some modes for magic, actually all the Mighty Magic stuff)

btw, have you checked your load order for errors with BOSS ???

You could clean your remaning 2 dirty errors with Tes5edit.

And then try that arrow thing again !!!!!

But leave that in your SKSE

[General]
ClearInvalidRegistrations=1

-----------------

If no luck try to disable all your mods, one by one - (but you should disable all Mighty Magick modes at once for example)

then try again !!!!!

Yes, I posted my BOSS results in a post above. And huh, I assumed that "Property pTG05KarliahInvisibilityspell on Script" thing was a Mighty Magick related thing, but if you have it I guess the mod is innocent then. Also yes I used to have mods but like I said, some of the mods listed in my papyrus log I've never had on my PC, ever, so it's strange that they're there. But like you said the log says to ignore missing files. I still find it odd though, as there should not be information about mods on my PC that I never had.

Could you please explain that a bit clearer because I'm not sure I understand. Like I said, there is no folder in my Data that is called SKSE, do I just make a new folder and call it that, then? And do I make a new ini file to type that command in, or is there a ini file I have to edit?

nope....

what you have to do is install SKSE first, not just make a folder. Get it here and follow installation instructions closely http://skse.silverlock.org/

When that is installed youll get the SKSE folder inside Data... then open that folder and create SKSE.ini and copy this in it ***, save & exit. (C:\Users\[you name probably]\Documents\My Games\Skyrim)

When you run Skyrim you'll need to start it using the SKSE launcher, not the normal Skyrim launcher. That's all.

I already had SKSE installed, I've been using it for ages, but I tried installing it again before your reply now, and there's still no SKSE folder in my data folder. I tried both the Installer and the 7z manual install, there is no folder named SKSE that I have to place inside data. Even the instructions don't mention anything about a SKSE in data.

[ Installation ] 1. Copy the .dll and .exe files to your Skyrim directory. This is usually in your Program Files folder under Steam\SteamApps\common\skyrim\. If you see files named TESV and SkyrimLauncher, this is the correct folder. Do not copy these files to the Data folder as with a normal mod. The "src" folder is only useful for programmers, most users can ignore it. 2. Copy the .pex files in Data\Scripts\ into the Data\Scripts\ folder of your installation. The .pex files are needed by all users of SKSE. 3. Copy the .psc files in Data\Scripts\Source\ into the Data\Scripts\Source\ folder of your installation. The .psc files are only needed if you have the CreationKit installed and intend to create or compile Papyrus scripts. 4. Launch the game via running skse_loader.exe. Steam must be running before launching Skyrim. If you use a desktop shortcut to launch Skyrim normally, just update the shortcut to point to skse_loader.exe instead of TESV.exe or SkyrimLauncher.exe. 

There is however, a SKSE folder here: My Documents > My Games > Skyrim > SKSE if that's what you mean?

Yes !!!!

I take a bath now, so i should see you later !!!!!

Okay, I made a SKSE.ini in the SKSE folder like you said, copy pasted in the stuff you said, and I went into the game and waited for 32 days (1 extra just to be sure ) I tried to trade him arrows, and it still happens. Instant crash to desktop. I checked the papyrus log to see if anything was different, but it looks more or less the same as before imo.

I guess the only option now is to disable mods and try without them, but I kinda feel like disabling a mod used in a save, will just make things worse.. so I'm not sure if that's a good idea?

leave that line yo your skse.ini for now. (you should be patient with that, because actually it works only as you play - and there is no side effects having it there, maybe your save file will grow a little, but it goes down after a while !!!!)

First you should disable all your Mighty Magick modes, and try again.

You mention to a previous post "it always happens at the same location."

If that the case, what if you go to a different location ????.

So here is the deal:

You disable your Mighty Magic modes first, load your save, after that you make a new manual save.

Then you exit skyrim completely, starting skyrim again, and load that last save.

This time try to do the same on another location !!!!

what will happen ????

Well, I've made a bit of a discovery. I tried now to give him iron arrows without taking my loot from him that that he was carrying first, and no crash at all. Then I gave all the stuff back to him that he was carrying earlier, and then giving him arrows, instant crash. I thought this was a clue, but apparently there was one thing I overlooked, which I then tested after..

When I gave him arrows without taking my things, I gave him ALL of them (144), and it didn't crash. When I tried again I gave him the same number I've been trying to give him ALL the other times I've been crashing, which is 100. Instant crash. I tried this several times, and it never crashes when I try to give him all my 144 arrows. Only when I give him 100. Apparently someone on the nexus forums also get instant crashes when they try to give IRON arrows to their follower, which is a different one, but it seems they can give them skyforge steel arrows without problems. I'm going to use the console to add other arrows to see how the game reacts to it, and going to test if the amount of arrows affect it or not, then I'll give you an update.

EDIT: I tried adding some daedric arrows via the console, and tried to do the same things I've tried earlier that caused crashes, no problems. Then tried iron arrows, no problem. I then reloaded, tried only iron arrows again, instant crash. This bug is really wierd.. but if it only affects iron arrows, I can live with it.. going to test a few more arrow types.

EDIT2: Tried the same thing as above, just with steel arrows, no problem, but like above, if I reload the save and then try iron arrows it crashes again. This time though, I also tried changing the numbers of the iron arrows, I first tried with 138, then 131, nothing happens, I decided to go below 100 so I tried 91, instant crash. So far it seems to only happen if I give him 100 or less, and only with iron arrow.

> When I tried again I gave him the same number I've been trying to give him ALL the other times I've been crashing, which is 100. <

Probably something went wrong with your save, because your mod's.

Read my nr 2 edit on that post, plus, on the Nexus forum post I mentioned, the other person dosen't seem to have the same mods as me as far as I know, and another guy replied saying: "Skyrim has had this engine bug for some time (at least since 1.8 was new). I'm not sure under which circumnstances it happen, but when it does, if you give another character 100 iron arrows you'll get a CTD. I'm not sure, but could be that this also happen with steel arrows." So that could be the cause.. in other worse, a Bethesda bug, not a mod one. If that's the case then I'll just live with it. I can just get him steel ones instead. I'll consider this a Bethesda bug for now at least, and keep playing. Thanks for all the time and advice you've spent on this though, much appreciated.

I can agree this is likely a non-mod related issue, because the game would often freeze when I tried to do this while playing the game on the Xbox 360.
