As the title says.
In order to be able to play another QB, I have to exit game and then go back in. After I do that, I get a message that I had quit /crashed the QB prematurely and that I will be punished if I do this too often. However, I have not crashed at all. I finished the game and then when options were grayed out, I quit to be able to play again.
I had a particularly good winning streak today, winning about 10-12 QB's in a row. (had to quit about 4 times because of the grey out bug)
When I checked my rank, I went from about 500 at the beginning of my session to 1300... this is after winning 10-12 in a row.
