So i was playing gmod trouble in terrorist town which is a gmod gamemode. I needed to get the counter strike textures so i installed the game and then when i went back on all the dead bodies where standing up with thier arms out slightely. Other people incountered this problem http://steamcommunity.com/app/4000/discussions/1/882966056388748016/
Found a fix.
I had addons installed and uninstalled the addons and reinstalled gmod.
