To all heroes:
We have just urgently fixed a logic error issue that may have been caused by over-optimization (such as black screen after battles, inconsistent store purchases upon multiple entries, victory in battle displaying defeat notifications, achievements not unlocking, etc.).
Please exit the game and update it. The current version should be a stable one. We apologize once again and will continue to monitor all community feedback, addressing any issues you encounter as quickly as possible!
