CTD on combat

[xen999]

Hello guys, I have an odd problem. I've been playing a modded game for a good couple of weeks now (up to level 39) and, while I initially had a few issues I managed to fix, some weird CTD started happening last night I never encountered before. Whenever combat starts and blows are exchanged, either me (or a companion) hiting the enemy or the enemy hiting me, the game CTD. I have absolutely no clue what could be causing this seeing as I have not installed any new mods, nothing that would give me some indication of which mod could be suddenly causing this. Any help would be greatly appreciated. Here's my loading order (I used LOOT to get a basic loading order and moved around some conflicting mods, though I'm sure it can be improved) :

If you start from an earlier save or start a new game. Does it happen then also?

If it does, try to disable your combat mods one by one to see if it can help pinpoint the problem.

Sorry I didn't report back sooner, crazy week...

So I did what you suggested and loaded a previous save and it looks like it fixed it... sorta. Occasionally, the game will freeze on a hit for like a good 5 seconds and then it will unfreeze itself and I can carry on with my game just fine. Other times, the freeze will occur and will result in a CTD. Thankfully I use Dynamic Timescale which includes an autosaving function and have it save every 5 minutes so I never lose that much playtime. I still wonder what's causing the freezes, but at least I can still play my game.

Just in case, someone runs into a similar issue, I managed to figure out which mod was causing these CTDs. After hours of troubleshooting, disabling every single mod I could think of that could affect combat, it turns out it was Enhanced Blood Texture (the script that's causing wounds to appear on hit I suppose). I have been free of CTDs in combat since turning that one off.
