I would love to see it if AE2 could fortune the discovered ores from Spectrum. Currently it just breaks the block as if it was stone/netherrack/etc because AE2 cannot unlock advancements.

Not AE2 specific, but I will add a way (machines / api) to auto harvest ores & other recources that use cloaking down the line.

This will magically start working in later mc versions, with the introduction of FakePlayers in Fabric API

Tested and fully working in 1.20. This will resolve itself :)
