I play game in emulator (Nox). Sometime (often) it crashes after viewing ad and autorestarts after this. Problem is: after restarting I have increased time delay for next view, but no effect on previous view. For example, I try to speedup chest decryption and press ad view. After viewing game crashes. It autorestarts and I see, that time for next ad view increased (50+ minutes on screenshot), whereas time of decryption not decreased (remains 20+).

Same problem with ad in game result screen. There is ad view for increasing loot. If game crashes after this, it autorestarts, returns to result screen, but neither increased loot nor view another ad.
