When the spell menu is open in Survival mode, if the player changes game mode to creative mode then their survival inventory is transferred to their creative inventory and can be swapped back if you do /gms in gmc with a wand open. The only thing that does not move inventories is the wand itself.. This is game - breaking. Please look into this, I cannot figure it out.

This plugin is not compatible with creative mode.

Put this in your wands.yml

wand:
  mode: chest

Thanks!
