I really hate to be that guy. I know the title isn't very helpful, but here's the issue: I'm assembling a small vanilla+ modpack on version 1.21.1. I got this mod for it, along with 3D Skin Layers and Not Enough Animations. I'm not sure if this is what caused it, but I at one point picked up a pig using Carry On, and now the mod just isn't working (I'm back to the default 1st-person view). Even if I make a new world and don't interact with anything, the mod just isn't doing its thing. It's still enabled in the mod menu...
