Hello! I have recently found a new problem where the Fabric API is breaking stone cutters.

Fabric API is only allowing one item to be made at a time, this issue sound utterly obscure, and I know it, but I am not lying. I'm not sure if this is a client sided issue, or if it really is Fabric API. Because when I only had Fabric API in my mods folder, the stone cutter was broken, but when I removed fabric api, it worked!

I am using version 1.21.4, I will update the mod right now, if it is still broken I will let you know, thanks for telling!

After updating to 0.115.0, it now works!

What version of Fabric API are you using? We quickly reverted a change that broke the stone cutter a few weeks ago, I expect this is the same thing.
