Yes, thanks for all the info. Ok, firstly, the training sessions were seriously broken and I fixed that bug in 4.1.7. I would actually suggest you upgrade to 4.1.7a just so that you are on the most recent version. There is a bug in the 4.1.7 package which did cause a problem for one player, so I'd suggest upgrading. You might see something odd with the new code, but the training sessions work fine. You might see something like 22/0 for the training sessions available. This just means you've used up all your training sessions. It will straighten itself out when you level again.
Ok, I will try that. However, since it's not really a huge issue for me at the moment, I'll probably wait until after helping to narrow down the misc experience issue, especially considering what I'll likely have to do to reproduce it more consistently (more on that in a second). I usually avoid alpha releases until they have been out for a while, but I'll take your word for it in this case and upgrade.
In terms of levelling up, do you mean you don't get the text that says "Click to level up" next to the Level label in the character menu anymore? The experience bar doesn't change (other than filling up), but the text next to the Level label should. Now the actual text change is controlled by script, so there might be a bit of an issue in there somewhere. Usually these kinds of problems are the result of either not installing Oblivion XP properly or installing another mod that changes the character menu after having installed Oblivion XP. I don't think either is the case here because everything else is working. However upgrading to 4.1.7a would fix any menu issues. Just use OBMM to create an omod and install this, please

Unless you know enough about how Oblivion's menus work to get this installed properly without

Yes, that's what I'm saying, sorry about the muddled description (it's been a while since I have actually seen it). To give you a bit of background, I picked up Oblivion again about a month ago after a 4 month hiatus (I do that often). I wanted to try out some new mods, Martegan's being chief among them. More specifically, I added MMM, Stealth Overhaul, Thief's Arsenal, Realistic Ragdolls, and Unlimited Rings. So, when I say it was "working before," I am actually referring to my play through prior to that last hiatus. I know one of those mods is likely causing the problem, it just hasn't really been enough of an issue for me to try and narrow down before now. On a related note, I am almost positive I was using DarkUI'd DarN with my last play through, but now that I think about it,I am not 100% certain. In any case, I do use OMOD versions whenever I can (OBMM just makes everything easier), and I did select the correct UI option when prompted, so I don't think the installed is borked, either (but I am not above admitting it's always a possibility).
Oh, and one more thing. Since they all seem to touch the same XML files for the interface (at least, that's what OBMM tells me), I enable DarkUI'd DarN, then Oblivion XP, and then MiniMap (in that order), since the MiniMap OMOD specifically asks if I have ObXP and DarkUI'd DarN installed when I enable it. I suspect that one may be the culprit, but I am not well versed enough with the XML schema for the interface files (read: at all) to know what to look for. However, if there is a file you want me post, or something specific you want me to look for, I will be more than happy to oblige.
Ok, now the infamous no XP from miscellaneous tasks. I have long suspected that MMM is the culprit.

Unfortunately I don't know what it is about MMM that could cause the problem... The miscellaneous stats script uses a lot of misc. stats to determine when you should get points for stuff, so perhaps MMM does something to the misc. stats. Maybe it's just an odd resourcing or timing issue - as I said I really don't know. However this does help me narrow it down and I can load up MMM at some point and see if I can find anything.
It seems to be related to killing things in my case. When I was using 4.1.5 (which was much more predictable about breaking), it only seemed to happen after I killed something. If I was just running around the city, breaking into houses, or running around discovering new places, everything would seem to work just fine. However, the second I killed something, all of my misc experience gains stopped. Once it did happen, it almost felt like the misc script just stopped running altogether. I suspected this mostly because even exiting out to the main menu didn't help at all, and I know that doing that had a tendency to reinitialize script variables and force cell reloads.
Just to clarify,my reasoning for thinking that it's kills is due to the way I play. Basically, I do things in "activity blocks" when I am playing. Specifically, most of my activities in the game fall into four basic groups (which I do almost exclusively for large stretches at a time): ransacking houses for Independent Thievery, exploring, dungeon crawl, or questing. Now, when I do a dungeon, I pretty much don't do anything else until I cleared out the dungeon first. I also tend to do a random combination of these "activity blocks" (e.g. ransacking > questing > ransackling > dungeon > questing > exploring), and what I started to notice is that any activities I would do after a dungeon crawl stopped registering experience points, unless it was killing something. If I stuck to just ransacking, exploring, or questing, everything would work fine (which is where I got my idea for the formal tests).
Now I will mention that you will only get the XP for finding a new location if the game detects that you've found a new location! I've had this happen in my game as well. For some reason, Oblivion itself just doesn't detect that you've found a new location. It adds the map marker, but you don't get the "Found blah blah" message. If you don't get that message, then the miscellaneous stat doesn't get updated and Ob XP can't award any points. However in your case, it sounded like Oblivion detected the new location just fine. When MMM was enabled in your test, did you get the message about finding the location?
Yes, in all of my tests, I always got the "Found Malaceth's Shrine" text in the upper right. Next time I encounter the issues, though, I will check the variables you described and let you know. As far as other misc actions go, I pretty much have the default INI settings (I've only upped the attributePointsPerLevel value from 13 to 15, and messageLogAutoHide to 0), which I think enables all of the misc actions. I'm not one for eating ingredients, but I do pick locks and read books/scrolls a lot, and I can say that none of them were working either once the issue manifested itself. I can also say that picking Nirnroot wasn't working, either. The only experience I could get from that point forward was from killing things. None of the other actions - specifically, picking locks, reading books, picking Nirnroot, or fame/infamy gains - seemed to register. I didn't try any of the other actions (I don't really like to bother with alchemy anyway), however now that I am a higher level and relying on enchanted weapons, I can add soul capturing to my list of actions to watch.
Now, as far reproducing the issue goes, I think I may need to downgrade actually, since 4.1.5 seemed the most consistent in manifesting the issue. For better or for worse, whatever changes were made in 4.1.6 and 4.1.7 seem to have made the number of kills more random, although I am almost guaranteed to see the issue after clearing out a large dungeon, most of the time. Conversely, the issue seemed to come up in 4.1.5 even after the first kill. However, I am not sure how much using 4.1.5 as a test bench will help you, since I am not sure how different the code bases are. Just let me know what you would like me to do (i.e. downgrade, or use the latest and wait for the issue to manifest).
I am also not above getting my hands dirty with the construction set. I am not that familiar with scripting, but being a programmer, I'm sure it won't be too hard for me to get up to speed (at least enough to read the code). However, I do not currently have it installed, and I just want to make sure before I install it that it won't do anything to make the issue disappear (especially considering how hard it appears to be to reproduce in the first place). I know most people would be happy if that did make it go away, but quite frankly, the programming side of me would be too annoyed with leaving a problem like that unsolved. :laugh:
EDIT 1: It appears I may be a big, fat liar. According to my archive folder, it seems I am running version 4.1.7a already. Is the initialization message supposed to show 4.1.7a, or does it still show 4.1.7? Is there another way to verify the version?
EDIT 2: I just realized I misspoke in my original post. I
did have to exit the game to reset between each test. Otherwise, once the issue manifested, I would no longer get misc experience, regardless of how many times I reloaded a prior save. However, everything else I described about my testing experience is accurate.
