[ + ] Changed how the internals of the Condition-Dependent system worked (when dropping heads) - it is now far more resource-friendly and should be smoother if it wasn't already.
[ + ] The plugin will display a warning if a custom head ID is not found.
[ + ] Fixed /hp debug not working in legacy versions.
I'm still very busy with other projects but do be assured, I'll be working on 1.16 as soon as it's out.
