Salem

My alt logged off in a bed on a claim.
When i log in, i dont have any rights on the claim, i'm stuck between the bed and the claim, i cannot move.
When i press log out, it says can't log out at the moment.

What happen to my character if i close the client?
Does he stay in game and accumulate madness, or will he just log out after a while?

you cannot log out when you are standing on a claim you have no permissions on. Your character will remain logged in (except for server crashes, which will toss all characters out of the world) and, yes, it will continue to garner insanity/madness.

I assume it went like this: you live on a claim by your friend, who took away your permissions while you were logged out?
Or you lived in unclaimed area and someone claimed the land while you were sleeping.
Neither of the scenarios are particularily promising from your point of view
