GMod AI screw up

Ok, I seem to be getting an error where the AI is screwing up when I load HL2 levels. They don’t have any special animations, and the people on the screens (such as Breen) don’t do anything or say anything. I tried reinstalling Gmod and HL2, and I tried removing the addons.

Anyone know what is wrong? AI is not disabled either.

Ok, I can’t seem to find any problem, but it is still there. Did anyone else have this problem before?
