Your fault for logging out in your house, someone is going to come and claim it, it's not the server fault it's the player's fault.
I said clearly that my minecraft crashed. That's not my fault, dude. Read dude. READ. That's not my fault. The server should've thought about that and have a command or some sort of way to then get out. Seriously dude?
you could just wait until someone unclaims the house and then leave then.
But, if it was owned in the short amount of time that you were crashed
(Assuming that you'd come back right away.), they're probably still i the house, so if you were to ask kindly to have them let you out, i'm sure that they'd gladly oblige.
If option 2 machine broke.
Try option 1 machine.
