For a while now, the world animations on Zoey and Coach are rather broken. They hold melee weapons strangely, they reload oddly (such as coach reloading the desert rifle like a pistol), and use throwables weirdly (zoey threw a molotov as if she was holding the m16).
Now I've asked plenty of people on the matter, and no it's not because of addons. At least i don't think its because of addons. I freshly reinstalled the game today, played 100% with vanilla everything, and they still had the awkward animations.
I've tried verifying the cache, reinstalling, testing certain mods, use of sv_consistency 0, and nothing is working. It's a miniscule problem, but it's grown to be greatly annoying.
