Known bugs (IMPORTANT — READ BEFORE USE)

This behavior pack is not very stable and has a lot of bugs since Minecraft / Mojang does NOT officially support custom stack sizes for some items. It can be done but may produce many issues.

The bugs (unfixable)

Throwable items such as eggs (all types) and ender pearls: these can't be stacked directly from the Creative menu. You need to manually drop and pick up 4 stacks of 16 to get full 64 stacks. They also cannot be moved inside your inventory normally — you may need to drop them, fill up inventory slots, then pick them up. When moved to chests you may need to use shift+left-click (or double tap on mobile) and they might revert to their original stack value (16).

Book and quilt: when stacked, typing in one book may replicate across all stacked books — useful for saving time but can be annoying if unexpected.

Enchanted books: stacked enchanted books may not be usable directly in an anvil; they often must be separated manually to apply them.

Honey bottles can't be consumed you have to saprate Them to their original stack Wich is 16

Everything else is generally fine to use, but please test in a safe world before applying to important saves.
