Very strange CTD

[Exodite]

What happens is that the game silently CTDs upon loading newer saves and occasionally under other circumstances. I first noticed it when I died and the game tried to reload the last save, which led to a CTD. Backtracking showed that the last 14 saves, plus auto- and quicksaves, all resulted in CTD upon loading. In effect I had lost some 5-6 hours of gameplay.

 

I called it a night and spent some time today replaying since the last functional save, this time getting further but now getting stuck in another spot where saving at any point after that will result in a save file that CTDs upon load. I've also experienced CTD when backing out of the overland map and one other time that wasn't related to saving, though I don't recall exactly now.

 

I haven't changed any mods from the last functional save until now, the only change I can recall making that I'm unsure of when I did was upgrading Mod Organizer to 2.1.2 (from 2.1.1). I'm fairly certain I was still on 2.1.1 for the saves that worked initially, and I'm definitely sure I was for the last functional save of today.

 

The character is carrying around a ton of stuff at the moment, long string of adventuring has resulted in some ten times her carrying capacity worth of stuff, and I flirted with the notion of there being some "container limit" I'm violating but that doesn't seem to be the case from initial testing (dumping off most of the stuff in a chest and saving).

 

I'd be more than happy to trim some mods or whatever but it's non-trivial to find the cause when there's no crash dumps or information outside of silent CTDs.

 

I've attached copies of my current last working save and the last one I did (that CTDs). These include my SKSE co-saves as well.

 

If anyone has any suggestions I'd be grateful!

Further testing seem to confirm that this is most likely SKSE-related.

 

I haven't been able to get the save included in "ctd.zip" above to work yet but after faffing about with my mods and such I've managed to create several saves which will make Skyrim CTD when using SKSE yet load perfectly fine without SKSE.

 

Loading without SKSE andchanging cell a couple of times, then making a clean save and relaunching with SKSE allows me to progress further.

 

I'll keep testing, currently my only SKSE-relatated mods loaded are;

 

SKSE 2.0.7

RaceMenu alpha 6 (converted, not using hudextensions ATM but it does work with alpha 6 from my testing)

SkyUI 5.2

 

I might, very grudgingly, consider playing without RaceMenu (or ECE) if it ends up being easier but I can't be without SkyUI.

 

I didn't realize it until now but I've never actually played the game without SkyUI, which led me to conclude that the default inventory management is system... not good.

Additional, possibly final, update.

 

Having progressed further with a regression to XPMSE 4.20, due to the known issue with SKEE (RaceMenu) and XPMSE 4.3x, I still ended up at a point where I started getting CTDs on loading saves and (very) occasionally at other times.

 

As of right now I've disabled RaceMenu completely and the game seems stable so far, I'll come back to this if I get further CTDs down the line.

 

I'll come back to RaceMenu with the next update but as of right now alpha 6 doesn't seem stable on my system.

 

It's weird though, as SkyUI is the only other SKSE-related mod I'm using so I shouldn't have any issues.

The main things I've run into that cause crashes are unconverted oldrim meshes, wrong skeleton type, or sound conflicts.  Oldrim meshes sometimes work fine, other times they're invisible or discolored, and sometimes they cause CTDs.  I've noticed even officially converted SE mods frequently still contain some unconverted meshes so I've started running everything through NIF Optimizer even if it's really converted just to see if it has any old style meshes.  I haven't seen SKSE ever cause a crash in my game, the closest I've come is that if you try to use the wrong version the game just won't even load.

I was having issues loading saves as well, it would CTD every time I tried until I removed SKEE from my SKSE plugins. I also reverted to the XP32 4.20 skeleton and the crashes went away. It seems there's an issue with one or both of the latest SKEE plugins and the newest Skeleton, I am unsure which but once I did that everything is going well.

 

I'm not sure what the ramifications are long-term but I know I can load my saves now.

[Bluegunk]

If you use PC Headtracking, that can cause CTD or save freeze if you have the setting in the MCM to Speaker Detection. 

If you do have this - try swapping that to Crosshair only.

 

Yes, XPMSSE and Racemenu (SKEE) Alpha 6 are not playing nicely together. I dropped back to XPMSE 4.2 and it is OK.

The problem is known and SKEE will be updated soon.
