Vagabond adventurer hangs out in the same location

I had the strangest thing happen: I asked Apro the vagabond adventurer to help me for a couple days, and after we were done he decided to stay near my home. He has been hanging out there for over a month! He seems to wander around in a 1 kilometer radius and occasionally comes by my kota. It's pretty fun seeing him every other day 
I wonder what caused him to not leave, since that's what all adventurers seem to do. I live in the most north-eastern corner of the map, so maybe that has something to do with it.

Guy decided that was a good place to hunt?  Or he's casing your stash

I have had the same thing happen, also when in the far north-east.  I suspect he is supposed to find nearby villages and set off for one, but being so far from civilisation he decides it is too long a journey and so just sort of hangs around where he is.
