Thanks for your report! I did look into it and it affects all of the Von Leon projectiles. It seems that crafting has a cap of 10 items as requirements. We will see what we can do about it.
I'm guessing the (recentish) removal of dark crystals was meant to fix this, but when crafting bullets now the power crystals aren't being used. I'll try to get a screenshot next time I craft
Crafted another set of bullets, forgot screenshot but: - If you don't have the power crystals in inventory, you can't craft (the check is there) - The power crystals still aren't consumed.
Thank you for catching this! It does seem like our original hypothesis wasn't really the case. Will have it noted and looked into.
