Hey everyone.
I got the following error, and all existing protections got removed when restarting the server:

21 11 23:49:11 [Server] Server thread/ERROR Error at SQL INSERT Query: org.sqlite.SQLiteException: [SQLITE_CONSTRAINT_UNIQUE] A UNIQUE constraint failed (UNIQUE constraint failed: pstone_cuboids.x, pstone_cuboids.y, pstone_cuboids.z, pstone_cuboids.world)

Did anyone experience a similar issue?
How do I fix this?
