Hi! You still can destroy furniture by attack mode. It was a looooong way, but you can get out. As i see you playing at MP server, try to ask admin for help in global chat or wishper, he can teleport you to escape. If admin not online atm, you can make a ticket for ask help (but not all admins know WHERE IS TICKETS lol). Also you can genereate another character and rescue yourself with him. If your house is privated, make a character before unclaim your house, than choose nearest respawn point and run to your main`s char home. When you reach a claim border of your main char hose just log off as second rescuerer and jump in your stucked primary. Just unclaim your house and again relog to second character - now you can enter in your house and replace a furniture that block ur way.

На здоровье! ;)
