Sorry I missed this one as it was in discussions, it shouldn't be an issue, the recipes use standard black pearls, the only thing I could think of is maybe a corrupted mod download or a stacking mod perhaps. I'll try the recipes again but I've used them without issue and so have others.

I tried the recipes in my table, with black pearls, and I can't replicate the problem. If you are using a stack mod it may cause the issue, but I've tried it with HG's stacks ant it works with that too. I hope you find the solution.
