With the release of the Easter Event, the Solar Flare was adjusted but created a bug where users had their Miner's Haven data corrupted when doing something with Solar Flare to trigger a calculation of finding a square of -1, which is i (In math, i stands for imaginary as in an imaginary number and squaring is multiplying a number by itself. You cannot multiply a real number by itself to get -1). Some users face this bug and Berezaa responded that he would come up with a fix ASAP. Apparently it took him 5 days to make a patch as it was released on April 20th, 2017. The process of restoring data can be done by anyone (As it would be really difficult to come up with a way of telling who specifically was affected by the bug). To follow the process of restoring data, refer to bergames.com.
