Server crashes with java.lang.NoClassDefFoundError: net/fabricmc/loader/api/FabricLoader any time a LivingEntity takes damage — including fall damage on a completely fresh character with no custom gear equipped. This makes the pack unplayable alongside the mods listed below.
The crash chain is:
miapi's ImmolateProperty (on-hit listener, fires globally regardless of held item) → EntityHelper.getAllEquipedItems → EntityHelper.getCurioItems → nucleus_trinket's NucleusTrinket.getTrinketList → AccessoriesApiMirror.getTrinketList → Accessories' internal ExpandedSimpleContainer.validIndex, which references a Fabric-only class (net.fabricmc.loader.api.FabricLoader) that doesn't exist on NeoForge.
Accessories (accessories-neoforge-1.1.0-beta.53+1.21.1)
Nucleus / nucleus_trinket (bundled inside miapi: nucleus-core-forge-1.21+1.1.14, nucleus-trinket-forge-1.21+1.0.5)
Aether (aether-1.21.1-1.5.10-neoforge, which also bundles its own jar-in-jar copy of Accessories 1.1.0-beta.48)
Taking damage (fall damage, mob hits, etc.) should not crash the server. nucleus_trinket's Accessories bridge should work correctly on NeoForge without hitting Fabric-only classes.
