I'm working on a 3D item pack inspired by ItemBound. For the most part, it works great. Then I updated it to 1.13. All the cit textures/models got wonked. Fixed it, but some are flat out refusing to work and for the life of me I cannot figure out why. I'm hoping someone here can help me figure this out.

Doesn't work:
type=item
matchItems=emerald
model=linkhat
texture=linkcap
nbt.display.Name=Link's Cap

Does Work:
type=item
matchItems=emerald
model=brilliantcutemerald
texture=emerald
nbt.display.Name=Emerald Brilliant Cut

The .json model and texture are exactly in the same folder it's set to load from just like the other one. The file names are named the exact same way(I copy+pasted 4+ times to be sure over the course of testing it). I cannot figure out what is wrong. I even tried making a new set in the same folder with different names, but it just does not work. It worked in 1.12, but refuses to work in 1.13.

Another one I'm now having issue is a shark model I made for the cod item. It didn't work for a while, but then I tweaked it. It worked. Now it does not work and I didn't even change anything.
