My Minecraft doesn't seem to notice Buzzier Bees at all. The recipes don't work, there's no creative tab for it, and I can't cheat in items from it like I can items from other mods.

Yeah, most other fabric mods work fine. I've noticed most of them (except Snow! Real Magic!, which also doesn't work) have a file called fabric.mod.json but this one doesn't. After I made that connection, I tried to copy a working fabric.mod.json file from another mod and change the filepaths. That made Minecraft crash instead of simply ignoring Buzzier Bees, probably because it actually tried to load it up but I guessed wrong about what to tell it.

1. The mod doesn't have a creative tab
2. This is a forge mod

Ah, thanks. It was 1.15 so I assumed. Sorry. (The other one Minecraft wasn't noticing is also Forge, and I didn't notice that either.) Feeling pretty dumb right now.
