I just hit level 10, and in game it did not display the amount I was rewarded for my progress. EDIT: I also did not receive a reward on the forums.
There's a known issue regarding latency for players and the server not replying fast enough. Will be fixed shortly.
I still haven't received my reward for reaching level 10, however I will log in tonight and try to get to level 20 and see what happens. Will post results here ASAP.
The rewards that didn't go through while this was broken will not go through. It is impossible for us to reward everyone that missed a reward during the broken period. We are curious if from this point on everything works well for you.
Thank you. Please continue to keep watch on your leveling. It seems some users continue to get issues, and others do not.
