Sure I Noticed this yesterday as well, on GKO Server.
- everyboy was red, but i was alone on the real red team, when a new player joined he was on the oppsite tems.
5 : 1 alle have the red color
but if they power up for shot, color changed to blue, if the shot was gone color was again red
_ no midd radar was also on the server
_ later i created a own listen server, the team color was ok, but the midd radar for the other player was not working, mine on the server was working.
