Exception in server tick loops

mods/pluggins:

This happens when my PC crashes on the off chance. Once my pc crashes, I would have to restore the Level_sponge files to a back up I have. It removes Warp data and home data from players and it can be frustrating. Is there anyway to prevent this?

If the server crashes the files will be left in an inconsistent state. The best thing you can do is make regular backups of the world data so if it crashes you can restore.
