Forgive me if this was posted somewhere, but I couldn't find it in searching.... it appears that the fairy ring ores are incompatible with mods that affect rock spawns. I'm specifically using Mineralogy though I've seen it happen with quark's own stones very occasionally (possibly related to geolosys mod groupings). The issue with appears to be that if vanilla stone isn't present at the level range for fairy ring ore, quark doesn't spawn the diamond/emerald. With Mineralogy installed, this seems to mean that 100% of fairy rings won't have the ores in the center. Is there any way to fix this without dropping Mineralogy? If not, I'd feature request a config option for the ore to be replaced with a chest with the equivalent gems in them, if that was at all possible to do.

I'm using 1.12.2 with the latest versions of Quark & Autoreglib. I don't have a link to my launch log because pastebin wouldn't accept that long a log. If there's a specific part you'd need, let me know.

I believe I know how to fix this. Will investigate.
