LibreExpFix (Fixes "0 Experience" Bug)

Note: This mod is no longer needed in Minecraft version 1.21 and newer, as the bug was fixed in update 24w20a (1.21).

About the Modification

LibreExpFix provides a compact solution to address the annoying issue of experience loss when traveling between dimensions. The mod fixes the bug registered under number MC-124177 in Mojang's bug tracker.
