To completely prevent incompatibility between bags and containers, such as bags of item type "SHULKER_BOX" cannot be placed through dispensers or alike, breaking the bag.
Bags are now only allowed to be moved in the following containers:
- Chest
- Ender Chest
- Barrel
- Creative
- Player
- Shulker Box
- Merchant
- Crafting (Player's inventory)
- Hopper
In addition to avoid issues with this change, hoppers can no longer move bag items, regardless of config settings.
