NPC and Player animations buggy

Whenever I spawn a metrocop or any combine their animations don’t work. Same with joining multiplayer servers.
I’ve tried disabling addons, and I’ve deleted local content and re-downloaded twice, to no avail.
Any help?

Where is your Garry’s Mod folder? In /steamapps/(username) or common?

I’ve been experiencing similar problems.

By the way, does it hurt if it’s in both?

No, the solution is to delete (or drag somewhere else) the folders and reinstall.
