Hello, I own the server ShulkerSky. It has been very popular over the past few days. Starting today the server has been consistently crashing. All player data was even erased at one point so we had to do a full restitution. It crashes at least once an hour and deletes everyones progress since the last crash. Is there anything specific that could be causing these problems? I'm open to any suggestions at this point, players are getting very upset.
