Can you elaborate more on what this means? Buckets are like one of the most hard-coded features of the game.

We need a tag for milk buckets to hold Skyroot Milk Buckets and Milk Buckets, and maybe a tag for Skyroot Water Buckets and Water Buckets in case it might be necessary but I haven't thought of any crafting situations where it would be.

Yikes. This is something that could probably easily be added into the mod itself, but I'm worried about compat with other mods. I don't know if our friends at Forge would be so willing to help us out with that (meaning, our PRs might get yeeted into the void for such a niche use case). Let me know what you think here or in chat since I might be personally invested for the sake of mod compatibility.
