Hello everyone. Disclaimer: Since I tried this for myself and just for a handful others, it still might not work for you. This thread doesn't guarantee a 100% success, although all of those people, that i helped out with these bugs, reportedly said that it worked out. I tried to find a solution for some bugging animations that some of the players are seemingly facing rather often (e.g. /actsit resulting in a weird dancy spinning move and dropping unconscious). The solution seems to be rather easy. Navigate to the Steam > steamapps > common > garrysmod > addon-folder > css-content folder > models > humans. If there are files in the humans-folder, just move them out of there and empty the folder. Remember to close the game before doing this. I would rather suggest NOT to delete the files, just in case this doesn't do the trick. Let me know, if this was helpful for you. Cheers.
