Do you need anything else from me about this bug?

Sorry, I've been really busy and haven't been able to mod. When I get time to mod again I'll check this out and may have questions.

No worries! Thanks :)

Ill chip in on this
If you use a Tinker Crafting Table the Dye used will be duped

• IronBackpacks-1.12.2-3.0.8-12
• TConstruct-1.12.2-2.10.1.87
• forge-1.12.2-14.23.4.2715-universal

The problem is the same as WayofTime/BloodMagic#1250

Fairly simple fix as well WayofTime/BloodMagic@924dc7b
