Sealed in

[Bonsoy]

It's unclaimed so it's open game. The fact that it was open and the keys are in there may possibly hint that the occupant may have left the area.

What happens if the person logs back in though?

Which is where there's a problem. Currently debating on out-right destroying it over time or just walling it in and being done with it.

Sounds like is was abandoned! I've abandoned homes like that before.. Usually with the key.

The guy that griefed me claimed over the cabin where I was asleep in a bough bed and over my hearth fire. I could log in but in order to even move I had to turn on criminal acts.

I'm not sure why it was possible for me to log in since I was now on someone else's claim... Thinking it over, yeah, I should have been unable to log back in to either point. Maybe it only works with villages? Someone with a village will have to test.

No, you can walk and login fine in a village you dont live in, its like you have trespassing but cant steal.
No criminal acts needed to move, positive

no, you can't "log in where you logged out" to someone else's village or personal claim (unless you have permissions on that claim)

Yeah got a nice key to one of the gates. Ones on perma-open though it seems so once I get 100 string from a hemp farm i'll wall it in with my own palisade leaving me one gate.
