I wasn't even in the screenie either though I was there =(.

This happend sorta like what happens in a big level and characters dissapear and you have to rejoin, maybe cause there's too much stuff ot handle. Lots of people in the server began using cheat codes (gametype was SP) like jjfire and stuff, and loosing a huge amount of ammo, so first some characters slowly started dissapearing (the o with the two dots above it, lower case w, y and z, numbers 6 - 9 etc) and the " marks turned to big Bs. was pretty cool, I have a few screenies of it too.
