by Mochi753

Functional Storage Downgrade Fix is a small Forge patch that corrects item stacking when Functional Storage's Iron downgrade is applied.

ForgeClient and serverMIT LicenseOpen source1.20.1

What it does

The patch changes the conditions under which Functional Storage's Iron downgrade is applied, which prevents items from being stacked above their limit. It targets Minecraft 1.20.1, and it requires Functional Storage to be installed alongside it. Every player and the server need a copy of the mod. The code is open source under the MIT License, and the original license text for Functional Storage is included in the project.

Key features

  1. Downgrade condition fix

    Adjusts when the Iron downgrade takes effect in Functional Storage, so the change no longer applies in cases that caused the overstack.

  2. Stack limit preserved

    Items stay within their intended stack sizes after the downgrade is applied, which stops the overstack problem.

  3. Small patch scope

    The mod only carries this single correction and adds no new blocks, items or screens.
