Don't know what's causing this.

This keeps happening. A while back it was being caused by Kennel Show Floor but I couldn't figure out what was causing it so I just ignored it. Now that I'm back trying to do more it's being caused by the Fertile Breeder. In one instance it was caused by talking to an NPC linked to FB Farmer and the other time was caused by FB Captured. I suspect it might be an animation glitch but I'm not certain. I can't even find anything about this glitch linked to FNV or FO3 (though there are Skyrim threads about something similar).

Sometimes this can accure after sex, with an error in the ragdoll section, If it's the case, you might be able to fix it by restarting the game, going to a save game with this issue, and f* the nearest person/creature you can find. You might have to repeat it several times though. 

 

if you didn't have sex at that time, I don't know. Perhaps if you share your loadorder, I (or somebody else) can see what this would cause.

This should be the current one. I can only assume it's a plugin.
