Who Cares About That
by jitterdev
Who Cares About That stops a crash that happens when the same item stack is added twice to a creative tab group, by cancelling the second addition instead.
What it does
Adding the same item stack twice to a creative tab group normally throws an IllegalStateException and crashes the game. Who Cares About That removes that crash by cancelling the second addition, so the group keeps its first entry and loading continues. It is a small Fabric patch for a single failure case, not a broader change to creative tabs or inventories.
The mod can be used on a single-player client or on a server. Either side can run it, and neither needs it. Fabric is the only loader it supports, with files for 1.21.1 – 1.21.5, and it is released under the MIT License but is not open source.
Key features
Duplicate stack crash removed
Adding the same item stack twice to a creative tab no longer ends the game with an error.
Second addition cancelled
The duplicate entry is cancelled, and the first stack in the group is kept as it was.
Narrow scope
Only the duplicate-addition failure is handled, so other creative tab behavior is left unchanged.
Compatibility
