Hey.. This is the first time I saw this bug. I joined a game room and player 1(red) appeared to be me. I was able to control the ready switch of player 3(yellow) until another me joined the room as player 4(green). And then i was able to control the ready switch of player 4 but not player 3 anymore. I was then kicked out of the room because the room was full. I came back to it again and the same exact thing happened again.
Sorry Lopdo, I know you're fed up with these bugs:(
