About this Mod
1.2.0+ REQUIRES DATAPACK
Important note on updating
(This only concers you if you're updating from previous versions to 1.2.0)
Due to major changes in how permission is registered through Flan, datapack is now required. Make sure you have the datapack in place when booting the mod.
Claims should remain intact, however, the permission setting for display case and pokemon spawn cannot be migrated currently, thus you'll need to re-enable them in your claims.
