About this project

What does Stack Size Fix add?

Makes item counts for items with invalid stack sizes visible.

Useful for playing old worlds on newer versions, where you might have "overstacked" items, but since 1.20.5 you haven't been able to see their actual count when they're not in your inventory.

Also useful on any server that sends invalid item stack sizes, like some Hypixel GUIs.

For shulker boxes specifically, Tweakeroo includes a client-side fix, and Stackable Shulkers Fix contains a server-side fix. If that's all you're after, and you use one of those mods, then this mod is not needed.
