I recently decided to start playing oblivion again, and I'm having some trouble...

First off, here's my LO:

SNIP

I've been having a few issues, like CTDs, missing meshes, etc... and I have no clue why... any help and suggestions would be much appreciated...

thank you

Missing meshes and WTF symbols usually mean something's not installed correctly, or you missed a required resource. FormID finder would help track those down.

As for your LO--have you run that through BOSS? If not, you should. Just make sure you have the latest masterlist.txt. I also don't see a Bashed Patch anywhere on there.

First, I'd really recommend Wrye Bash if you're not using it already. For one thing you get load orders with version numbers with it, which is very helpful when trouble shooting. But it has loads of useful features so it's pretty much a must if using many mods. If you already have it, post your load order via it instead: right-click file-header > list mods > paste into post.

If using the latest MMM, which is recommended, make sure that you have renamed the bsa correctly, in your case Mart's Monster Mod for OOO.bsa.

For OOO, make sure you have OOO 1.33 Complete installed and not just the OOO 1.34 Beta 5 patch.

Also, update Mart's Monster Mod - Diverse WaterLife.esp to http://www.gamesas.com/index.php?/topic/1116296-relz-martsmonstermod37b3-public-release-3-relz/page__view__findpost__p__16393704 if you haven't already.

Regarding stability, I'd recommend getting a stable core install before adding other mods. In your case I'd first focus on getting a stable MMM/OOO/Cobl install.

Also:

Natural_Weather_HDR_by_Max_Tael.esp - Has some issues IIRC. Consider switching to All Natural instead.
Living Economy.esp - Has some issues, use Enhanced Economy instead.

Mart's Monster Mod - No Reavers.esp
Mart's Monster Mod for OOO - NoReaversInGates.esp - No need as you're using ^.

okay, gonna switch to enhanced economy, as for natural weather, I used the recommendation of BOSS (Ryu Doppler's bug-fixed version) http://www.tesnexus.com/downloads/file.php?id=14918

and I removed the redundant no reavers plugin

New LO:

SNIP

currently CTDing the minute I save...

First, you should update http://www.gamesas.com/index.php?/topic/1119240-relz-oscuros-oblivion-overhaul-133/ as the latest MMM release requires it. Then I'd recommend starting out with fewer mods - it's always difficult to trouble shoot with lots of mods from the start. Make sure you have a stable core install of, say, MMM, OOO and Cobl before starting adding other mods.

okay, adding ooo 1.34b5 fixed... pretty much everything. So thanks for that. Now, I have a slight issue, and I'm curious if there's a patch for it...

It seems M.O.E. Delayed quest start slightly conflicts with better cities (anvil specifically) as once I left the ship (it didn't ctd this time ) I found two ships in the same spot. One from better cities called: Night's Scream, and one from MOE delayed quest start called: The Floating Log

If there's a fix, I'd love it. If not, I need to know if Night's Scream is important, or can I just delete is in the CS?

Well, pretty much every issue has been solved, but I need a little help on misc things... The above post is the first one... still need to know if that ship is important...

I'm also having an issue with Light spells... they aren't working like they do in vanilla oblivion, and I don't know why... I noticed it when I tried out the starter light spell. instead of it being an orb of light surrounding me, it was a VERY small ball of light following my crosshairs... not to say it isn't an interesting idea, but when the light ball is only 2ft wide, and the spell says 30ft, there seems to be an issue...

Any help would be appreciated
