Got this error when logging in for the first time (after removing my /world folder)

Doubt its anything serious, but yea its atleast an error, so thought I would report it.
(I think my spawn was inside the ground etc, which caused this.)

That's just a notification, not sure why there is a stack trace.

Yea, I reported it due to the stack trace as I wasnt sure why that would show up.

Doesn't seem to be an actual issue, this is mainline Essentials behavior as well. Kind of an edge case.
