I hope I'm not being paranoid right now. My psychologist says that I am, and usually I agree.
I just played a game on one of the (is there more than one?) SATGNU servers. Due to team imbalances I switched teams, from aliens to humans. There were about six players in the game. The switch went smoothly, and I went on fragging aliens.
Then I received a "the team has too many players" dialog, the annoying one you have to click 'OK' to close. In the middle of the game, just as I was aiming at a Marauder doing a flight over our base. I thought no more about it, but it happened again. I kept on playing and it was quiet for a while, but when I was outside the alien base doing a head to head with a Marauder, the same dialog appeared again. SIX TIMES IN A ROW. Needless to say, my body was used for carpeting on the floor.
Have any of you had an experience like this one? Smells like exploit to me.
