I can't recall if this is currently a feature but... Would it be possible to add a warning message for players who try to warp or /tpa without having a home location set?
Something like:
Something like:
"You do not have a home location set, are you sure you want to warp away?"
It may alleviate the instances where players need help finding their houses because they warp to a shop/farm/etc without setting a home.
