I believe i've noticed the following behavior a few times already, and today it happened again:
- had less than 2000 xp left to the next level
- lost game next game (coop)
- finish screen shows around 2500 xp earned, but still shows old level and a couple of xp left to reach next level
- after another game the finish screen suddenly shows that i've already reached the new level and counts on from there
-> no reward for that level given
Has anyone else noticed this? I can't be 100% sure about this since i didn't document it properly, but i'm almost certain there is a bug in there somewhere.
