Basically playing custom games is not possible right now, too many players desync, depending on the map.
Also it happened to me that i desync no matter what i played until i close the game and open it up again.
Sometimes when you are downloading map, you don’t join the game, you are moved to the channel, feels like a kick but you know its not.
I’ve also seen a game notify me about not accepting the version of the map i have so i couldn’t connect and download the version host is hosting.
