Is it normal that despite the fact that you were in a game, making progress, that if you get kicked or DC from the server for whatever reason, all the progress is lost? How does that make any sense? Do stats not update right away? Its quite frustrating leveling up the same level more than once.

Progress only saves after a round.

Especially bad, when you have a ultragood round, get votekicked, and everything is lost.
Stupid, but thats it.
