Thanks for reporting, I'll look into it

Fixed in 0.18.2

Huh, that’s weird. Could you share your whole latest.log so I can see what exact versions you’re using? (fabric API, fabric loader, minecraft, treechop) Also if the error message has changed at all

The name of the newest version is TreeChop-1.20.1-fabric-0.18.2.jar TreeChop-1.20.1-fabric-0.18.7.jar

btw its in 1.20.1
