Got a dupe glitch between Actually Additions and Shinies Bag. Posted on his github, he told me to contact you. He suggested a fix, but I know nothing of code, so here's the link to that post.
Adore your mod, btw.

I don't make Gemulation, but I'll pass along the information.

My mistake! I assumed that Gemulation/Gems were by the same person! Thanks for the quick response.
