at the end of every game most of the time it will just freeze at the scoresheet and not advance me to gain xp, go to the lobby...etc

heres what usually happens

happens to me also but not everytime.

its really annoying...every time you have to quit (90% of the time) because it won't advance you lose all statistics from that match so basically I cant level at all.
