Thing is I didn't play JKA MP LOOONG time and when I was playing this all was fine, I have also installed jkacademy1_01 patch.
Console says nothing, iwabo, as I said the only thing I did in console was /connect. Connecting to server goes relatively fine (awaiting gamestate, awaiting challenge... ) but my game crashes right after I connect (i.e. I already popped up on server). Only windows-warning pops up: *JKA stopped working*
EDIT: now this is funny, i launched the game again, and joined game on random 3 servers, aaand played
okay, wtf....
