Fixed a bug with reveal sub type modifier that could consume other items to create copies of the card.
No item tags were changed, so if you dont have any bugged items you should be fine just updating and all previous items will be fixed.
Resource pack did not changed, you may use one from version 3.14.
Please read description.
tested only on core leaf 1.21.1 and 1.21.4, but I REALLY dont see a reason why other might not work
