Hello,
it seems my level of terran got reset, and is acting really weird now. I was at level 49 and close to 50. Happy. But as of this morning im back at level 1, 2 and after each relog im at the same low level again. I gain XP after each match, which boosts me to level 3 or 4. But seem not to get to level 50.
edit: Seems solved as of this evening.
