After extensive searching in a creative setting using ore-tracking methods, I have concluded that the generation of Luminis Ore is not occurring.

Possible Retrogen would be recomended

Yeah, this just got found out yesterday and I'm working on figuring it out. It'll be back next update, but retrogen is not in the plans.

Understandable.

I've tried messing with the gen via datapacks (attempted) and found that I can't get the generation to happen even if I set it up to use another mods ore distribution to see if anything happens (as my method of going about things is to rip and tweak in a trial-and-error fashion to get a understanding on things)

My attempts failed and I'm not quite sure why; though I would recommend changing how the feature stuff is named as it's a bit confusing to have them named so similar to one another 😵‍💫
