We spent three hours working our way up to the final fight of an explorable dungeon, and one person had to leave. We had a replacement lined up, but as soon as that person left, the whole party was dumped out of the dungeon back to the map we entered from and all progress was lost!
I don’t see why this would be designed this way, or what purpose it serves. Surely the other 4 of us should be able to continue and finish what we started?
