There was a problem with keys falling out in the "Last resort" mode in season 3 to open appearance costumes. It seems like they should be given every three levels, but the keys do not give at all. I have already raised 40 levels, but only got 4 keys.
Hey Suslik0ff!
Thanks for your report. We're aware of this one and are working on it. Your patience is appreciated!
