Yeah, I'm sorry this is probably in the wrong section, but the bugs and troubleshooting section isn't working for some reason. 0.0.
Anyway, On Delorean88MP's BTTF mod for San Andreas, after I install it, whenever I hit a vehicle, it floats away. Kinda like zero gravity.
But it only happens when this particular mod is installed. I have no other mods on the GTA SA.
I demonstrated this glitch in THIS video.
