yep

how to fix it

After testing it myself, I've come to the conclusion that it's from CSS content not being compatible with the mod
The mod worked perfectly after I uninstalled it, tho it is a big issue since CSS content is pretty much a necessity in gmod

Cool

I know hot fix these animation, it's not because of the current addon.
The fix is pretty simple.
1. go to C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\addons\css_content\models\weapons
2. Delete all the files starting on "W"
does not work if you have legit cs:s mounted (maybe)
