An extension was written to the same path as the material it extends,
one pack over. A datapack file is identified by its path, so that never
added an extension to anything: it replaced the material with a stub,
whichever of the two packs loaded last. The stub then named itself as
its own parent, which MIAPI reads as a cycle and drops, and the material
was gone entirely for anyone with both mods installed:
Unresolved extension cmmodular:metal/arcane_metal for target
cmmodular:metal/arcane_metal (missing or cyclic dependency)
That is arcane metal and mithril, the two materials Create: Wizardry
adds forms of, and it explains why they worked before the extensions
existed. Ice and Fire's amethyst was never affected - it extends a
miapi: material, so its own cmmodular: path collided with nothing.
The generated name carries the pack that owns the extension, since the
pack is why the extension exists and there could be another from a
different mod later. Nothing else about the files changes.
