Their compat breaks due to some changes in Chalk 1.5.0. That's on them to fix.

It was probably not a smart descision from me to rename block package though. For some reason I haven't thought that it would cause a problem somewhere. But it's too late to change it back now.

I've let the mod author know of the issue on Curseforge, and directed them to this issue.
