Had a search but didn't find this problems. I've been rather lucky glitch wise. A few random crashes but after some of the horror stories I considered myslef lucky.
So my problem is when ever I open my pipboy, my characters arm doesn't come all the way up (see picture). Whatever is causing this also seems to be throwing off V.A.T.S with everything going high.
Any thoughts?

I've tried realoading older saves/quiting a restarting with no effect.

Any mods installed?

Anything at all in your "meshes" directory (if one exists)?

Yep got some weapons and hair mods going, but had them for a while this just randomly started.
UPDATE - Did a clean reinstall, seems to have fixed it.
