Doesn't work with biomes created by other mods like biomes o plenty or terralith. Suprising this mod doesn't only work on chunks and depends on biome as well. When using ore vein finder it shows nothing in a any chunk that's in a modded biome. Only worked when over vanilla biomes which with biome o plenty, is only oceans. I set the generation chance to 5 instead of 5000. Don't know if that made it worse or better but either way i got the results shown in attached SS. 1.18.2

The mod uses the 'forge:is_overworld' biome tag, which is missing on BoP biomes. They only fixed this issue on 1.19 Glitchfiend/BiomesOPlenty#2053
