NPC Twisting Arm Bug

[Nompo]

After 30-60 mins of playtime, virtually every NPC in the game will start doing this:

Doesn't matter if I fast travel or reload, they will not stop doing this until I fully restart the game.

I have tried troubleshooting it for hours. I can not find its source or fix it. I've tired disabling pretty much every mod to pinpoint its cause to no avail.

IT IS DRIVING ME INSANE.

Please, does anyone know what is causing it?

EDIT: ..forgot to mention, that usually when this happens, my game in general seems to get really bogged down. I'll start getting a lot of stuttering and fps drop. And usually, if I don't just restart the game to fix it myself, the game will often just crash not terribly long after this bug starts. So it might be some kind of memory problem?

Possible your bashed patch. have you tried disabling it to see how that goes?

 

What's in it, by the way?

[Nompo]

I did try disabling the bashed patch. Even though the problem started before its creation.

I don't recall exactly what's in it. Was only like three smaller mods.

[JimboUK]

Go to Data\Meshes\characters\_male\locomotion and see if there is a mtidle.kf file in there, if there is try renaming it so the game uses the one from the BSA.

[Nompo]

I did find that in the meshes folder. I renamed it to see if it helps.

Also, I found that the Cyberware mod has a compatibility patch for the Quickthrow mod that I did not have installed.

And since Quickthrow has custom animations for throwing explosives with your left arm (THE ARM THAT IS BUGGING OUT ON THE NPCS) I'm hoping that the patch might also be the solution. Though I swear I fully uninstalled that mod with that thought in mind to test it at one point.

I'll give an update once I put some time in to see if the issue persists or not.

 

EDIT: Neither fixed it :wallbash:

I thought of that file because it seems to stop when they walk but obviously it's not that, I don't know what to suggest, I've seen a lot of strange things over the years but never that.

[Nompo]

It did stop in that particular instance when they began to walk. However, that is not the case a good portion of the time. They'll be npc's walking about with their left arm wobbling around in that disturbing manner as well.

 

And yeah, I searched, using a variety of different terms, to find someone who had a similar problem but could find nothing. The closest thing was, at release, when players would start a new game only to find the good doctor's head to be spinning during the opening dialogue. But it seems that was quickly patched out by the developers themselves.

[JimboUK]

I'm grasping at straws here but try renaming Meshes\characters\_male\Skeleton.nif just to rule out an issue with that.

[Nompo]

Unfortunately, I already tested removing that from the meshes folder entirely.

[JimboUK]

At this point I would disable all of the mods except for the official DLC and start a new game, if it's working OK then enable a few mods and test it, keep doing that until you find the culprit.
