Alright so i have custom mobs and stuff connected to the resource pack, and other things that was working perfectly fine, and then I attempted to insert an assets folder of something new into the items adder resource pack, and it just straight up fucked with everything. It seems all textures are fine but the custom stuff, such as like mob textures, or some custom weapons I added. Idk, but I don't really have anywhere else to ask this.
- what I've tried, I've tried putting the new assets into ia again

I've downloaded the assets from model engine, and pasted it in ia again (fail)
also I couldn't find the tag "question" like others did, sorry for not using it
