When you join a realm and there are members that aren't on your friend list and you select the ones you have on your friend list, but then de-select them as soon as the other members appear on the invite list. When you do this, the counter at the bottom of the screen will enter negative numbers. I'm pretty good at computers, but that isn't important right now, I believe this is a glitch due to the counter not expecting the other players to enter the list and subtracts too much. Thank you
