NPC Animations are jerky

Hi, so for some reason or another, a few days ago all the npcs I spawn have jerky animations, as if the framerate is 10, no matter what the actual framerate is. Is there anything I can do to fix this? It’s kind of bugging me. It makes me feel I’m playing Doom.

Are you making them use custom guns? some guns dont really work with the npc.

No custom guns or anything. Just started being jerky one day

is there possible any extra console errors or statements?

No errors, nothing strange, except the npc anims are jerky.

Are you using custom models for them?
