I cannot explain it, I've never experienced anything like that before, I just slided many times outside of the map and fell to my death, or slide past a ledge grab. Speaking of ledgegrabbing, it seems to not work at times.
Also, Server Operators, I really would like you to consider not forcing players to play by reducing lobby time to 1-2 seconds, it really is annoying and I have to forfeit a match just to get out.
