Always read what bot says. If you aren't sure what happend type !autoban. Bot will tell you if game is considered as draw or autoban is off but you should play till the end coz stats will be saved (if you leave in this case you won't get autobanned but you'll lose PSR) or autoban is on.
+ you'd better check it with !autoban command coz somethimes there are ppl who says same stuff that bot says (Autoban is OFF, you can leave...) just to confuse ppl and then they leave, got autobanned, enemy players rofl and easy win...
