Some quick server reminders:
If you die and lose something from your inventory, we won’t spawn it for you. That’s life.
Label your houses/builds with a sign with your username so we can notify you if anything happens.
Place a noteblock in your house so it logs people coming in, using your stuff, etc. That way we know who griefed you.
Lock your chests/doors/buttons/levers by hitting them with a stick.
