Model glitches

Before I start, I just hope that I posted in the right section for this kind of stuff.
Anyways, I had recently got back to playing Garry’s Mod, loaded up a map, and spawned some combine, but to my surprise, their animations/models were fucked up.

I had recently purged my addon list, so I don’t know what was going on. If you guys have a solution, I will be eternally grateful.

EDIT: Okay, I found the source of the problem. It was one of my legacy addons. Case closed.
