Revert MC-101556
by litetex
Revert MC-101556 undoes a single 1.21.5 fix so nether portals and chunk loaders behave as they did before.
What it does
The mod reverts the fix tracked as MC-101556, which changed how nether portals and chunk loaders work in 1.21.5. With the revert in place, those mechanics return to their earlier behavior. The change is a single patched line of code, and the mod is otherwise minimal. It is server-side only, so players join without installing it, and the server alone needs it. Files target Fabric and 1.21.5 only, with version 1.0.0 dated 2025-04-24. The code is open source under the Apache License 2.0.
