GeckoLib3 support was dropped with outdated buggy code left in the mod.
The GeckoLib team refuses to remove the unused code that crashes other mods because they don't want to look like they still support 1.18 or 1.19, even though their code breaks other mods.
This addon removes the unused buggy code so that GeckoLib3 doesn't crash other mods. This allows mods like Cosmetic armor to be used with GeckoLib on 1.18.2 and 1.19.2 without geckolib crashing.
