[BUG] Unlocked characters trouble

Hello,

I’ve to report a bug. I unlocked Ambra by Command level, and never even played with any character of her faction. The achievment list of unlocking her by playing 5 times with her faction was still showing incomplete. Then I’m played 5 times with her and that gave me a error message from the server and didn’t counted that round, making me lose all that i’ve collected in the round. I’ve even completed her history missions but never got her special taunt.
