Hi.
I'm trying to change the glint texture on items with the specific NBT tag. So I made a couple of mixins like Quark does.
But minecraft crashes with InvalidInjectionException. 

Forge version: 1.16.4-35.1.13

Thanks, @diesieben07 but how that could help me? I'm trying to make a custom glint texture only on items with my NBT tag. 

Solved.
Tip 1: Don't code for 20 hours in a row. 🙃
Tip 2: Make f sure your refmap.json file name equals to refmap field value in modid.mixins.json.
