[media]There is diffence between a stored enchantment and an enchantment, enchanted books only have stored enchantments, not enchantments themselves, they can't get flame and when hitting make the enemy burn. /enchant adds enchantments, not stored enchantments.

Yeah, I found out that when I saw that ALL OF MY ITEMS disappeared (chests, furnices, inventory etc)... Not gonna play survival for a while now then.
Armor stands may also be affected by this - in addition to the book on enchantment tables.

I don't know what program may cause this, but I can't find any programs that may cause it I think tbf.
