So I made a custom modpack based off Sprout - Explore for More containing the Abyssalcraft mod. I'm encountering a strange worldgen issue where all abyssalcraft worldgen (ore and biomes alike) is 100% missing from my save. I tested this issue by testing an ocean cave (for finding coralium ore) on my modpack world to an ocean cave on a world with just abyssalcraft and journeymap installed and no other mods. Sure enough, the abyssalcraft-only world generated ore and biomes.
Due to the sheer number of mods I have installed in the pack (almost 200), solving this issue via process of elimination would be a nightmare (between starting the game up and testing every mod with abyssalcraft especially). What I can say is that I find it extremely unlikely that this problem is a matter of me simply being an impatient explorer. This is because I found coralium immediately upon locating the ocean cave on my single-mod world. Coralium is THAT common, and the fact that I haven't found any coralium in my modpack world over the course of many IRL months of cave mining on my modpack world must mean that there is a clear issue. So before I compare mods one by one, has anyone encountered this issue before? Is there a known mod(s) to cause this conflict; is there an easy solution for this problem?
