If somebody shoots themself and then immediately leaves (unsure if it has to be last shell, in my case it was), the turn will go backward one, and the shotgun will invert the normals of its model. If this happens, then you're effectively able to shoot as many times as possible, allowing you to win. This needs to be fixed as soon as possible. I've attached the log file and a quick clip of it working, although the host kicks me quickly after the bug happened. In the same clip, I killed the guy in front of me completely. The log file is also aligned with the clip itself.
