I loaded the game after accidentally killing myself and was presented with an interesting change, the revolver and shotgun had changed some properties. My revolver fires normally, sounds like a normal revolver but upon inspection of bullet hit decals on walls and floors it appears to fire like a shotgun. Using the revolver on enemies shows me that the damage is like that of the shotgun not the revolver. Vice Versa for Shotgun. Single shot comes out of the shotgun and is revolver accurate.
I am using the “More accurate shotgun” Mod from the Steam Workshop by Kaleidiscoop. I don’t know how this could affect the glitch but I think it could.
I was also presented with vortigaunt and some HECU models glitching into a single pose.
Will upload images and all that extra information soon but is had been a long night/day and I have work to do.
