I don't know what happend, but right before server restarted I had 37k mym's and when the server came back up again(after restart) then I noticed I only had 27k mym's. Can you check the logs and fix this issue...?
Check if they got turned into claim blocks please. Edit: le nope, checked with the player in game. The missing MyMs are not in claimblocks.
on direwolf I changed the system a days ago to a new one which shouldn't have any issues. It is only on dw20 yet, so in case issues arise we kept them minimal. This setup will carry over to infinity, soon. If no big issues appear.
