Hi WP,
I usually relogin from Central Lab to back to town and click Destroy Dungeon button to quit my Instance and then disband party (solo party).
Unfortunately, I was disconnected right after relogin (this make me relogin twice) then the Destroy Dungeon button went missing from my ATL + B window.
Happened since some time ago and I have to wait for an hour in order to break the Instance and disband my sole party.
I suppose, this shouldn't be the setting, we should be able to destroy a dungeon anytime as long as we are outside of the Instance, am I right?
