About this Mod

This is a backport of Advancements Debug for Legacy Fabric versions 1.12-1.13.2.

This little mod rewrites one function of the advancements logic to make advancements checking faster, and use less recursion. It should prevent StackOverflowErrors with advancements.

If net.minecraft.class_3347.method_14931 appears in the crash log, this mod is likely going to fix it.

This mod can be installed on the server-side only if you are having issues on a server, but it can also be useful on the client when playing in single-player worlds.
