That's how it was for Kai since it was his prison but wasn't Bonnie about to commit suicide and everyone was concerned because it was assumed to be permanent?
Originally, I thought everything reset every day and only your memories of the past remained intact. If you died, you came back. If you burned down the town, it was restored, etc. Yet Bonnie was able to drive across the country and back in the one day of the world so I guess, like most of the VD universe, the rules are whatever the plot calls for and subject to change.
