[ThinkWithPbody]

I've had this problem for the longest time and forgot to report it!

[Sunconure11]

Having this issue too.

@theorbtwo

[aelfwyne]

Same. Crashy crash.

[theDerpu]

PLEASE fix this.

[shanoaice]

This even affects Farmer's Delight, as its generated datapack seems to trigger this bug too.

[Lgmrszd]

Having same issue on All Of Fabric 6 (1.4.3), identical error in the log.
