Thieves, here's the summary regarding the progress loss issue.
The data center where our servers are situated and maintained has faced an accident on Feb 23 approximately at 6 pm UTC+0. Something went really wrong and it has affected some players. We haven't got enough time to blame the company that owns the data center, all our team's efforts are aimed at solving the problem. We are aware of the situation with the progress rollback. We will restore the lost progress this week, the process will take a few days.
Please note, that the progress will be restored to the state it was on February 20th. We will also restore in-app purchases made after February 20th, although it may take more time. Also we are going to give a good compensation to affected players.
You can track the latest news on the situation on our Facebook page and on Twitter:
Please do not try to reinstall the game during the progress recovery.
Thank you for your patience and please receive our sincere apologies!
