Well, today I've reached Level 30 with my Ares character but something weird happened.
The exp screen after battle returned me to Level 0, and my exp points became negative (-500/0).
Champion screen shows me at level 30, no problem there.
Also I have not received level 30 abilities points, I've played two more times and was rewarded +1 ability point when I reached level 1 again, however I have not received this point at all, meaning I have a maxed character with no hope of purchasing the remaining abilities. =(
This is super frustrating, so please look into this, guys!
