Missing Animations on Addon Weapons!

I recently tried to make a video in GMod, discovering that on custom weapons put in addons (for example Realistic CSS SWeps, Machinimahands, Kermite’s Weapons, etc.) my player model is missing world animations! When I don one of these weapons, my holding animation (world model) reverts to a pistol holding position! What can I do? May I add that I have tried cleaning out Gmod and deleting recent downloads.

Latest update broke this, you will need to edit the weapons to fix them. i made a hacky fix so you dont have to edit them though:
