This is a fix of a known bug in Create 1.21.1 (Create#9695) where items with NBT changing constantly (e.g. Relics Mod, pocket generators...) get desynced in the inventory and cause client to disconnect from IndexOutOfBoundsException if the item is in the last slot of player's hotbar.
This project was vibe coded, it's only published to be used in my modpack.
