Yo, so I’m sure this has been reported before but oh well (couldn’t find a thread on the first page, too lazy to go beyond page 1). Sometimes when the teams have been decided, the UI won’t properly show the team colors correctly. It’ll sometimes show everyone on one team color, or mismatched. This happens I would say 3/5 games.
Here’s a Steam screenshot I took a little bit ago showing this bug. Again, this is just a UI bug. This doesn’t affect the teams after the game has started or anything.
