Good evening! I can't seem to be able to delete world directories just like i could in 1.15.2 (Using spigot's api), Are all external worlds counted as vanilla worlds now? I'm getting a security exception which should only happen when deleting the vanilla default worlds. (Yes there are no players in that world, and i attempted to unload the world before and even after the deletion, chunks aswell) I tested a couple of other plugins like multi verse and they all have the same issue where the session.lock gets left, Yours sincirely, NikV2
