I recently upgraded to a level 12 training camp, trained a rare hero and waited the forever time limit for it to train…then when I pressed collect, nothing happened.
I didn’t get my rate hero. What happened? What do I do now
If you have looked inside heroes tab, found no new heroes—and did not feed any heroes to another hero (you can accidentally feed away your new hero this way!)—then you will want to contact Game Support for help:
check the in game recent activity. Go to Options → Support → Recent activity. Just check you didnt get anything?
That looks a little like a visual bug where the ! is supposed to be on the Raid thing (for the raid tournament). Try closing & restarting the app completely.
If you still aren’t sure/ don’t think you got a hero, probably best to launch a support ticket in game:
