I've been trying to get OSV and Mystcraft to work togheter. But when I turn of vanilla ore generation in OSV I can't get any ore at all to generate in Mystcraft dimensions. I have the OSV ores set up with 3 generation rules. One "normal" that blacklists dimension 1 and -1 one one each for dimensions 1 and -1 that whitelists those since the heights ores should generate at differs. I get correct ore generation in Overworld, Nether and End, but I get nothing in Mystcraft dimensions. I thought the rule that Blacklists dimension 1 and -1 would make it generate in all other dimensions (and it generates in the Overworld).
If I enable "world { B:enableVanillaOres=true }" I get vanilla ores in Mystcraft dimensions, but also in all normal dimensions.

I have created Symbols (pages) for all my custom ores with json files through Mystlibrary and Pages mods. And I can get Mystcraft to generate the ores as Tendrils. But OSV does not generate any ores in the Mystcraft dimensions.

The reason behind using OSV is that I want the ores to generate in Nether and End, and that I want the ores to generate in what looks like native stone (Andesite, Diorite, Granite....). So pretty much the reason OSV was created.

I have custom ores for Thaumcraft, Thermal Foundation, Forestry and Applied Energistics 2 defined and all those works. But I have also tested with just OSV and Mystcraft with only Vanilla ores and can't get it to work.
Since I want to play with Forestry and Thaumcraft I'm stuck on Minecraft version 1.12.2
