Looks like this bug may have been the reverse -- there was a bug where you could send an adventurer to a dungeon if they were already travelling to a dungeon. If you did that, it could "lock" the dungeon from further attempts (until you refresh anyway since dungeon/adventurer status isn't saved right now). I've fixed this by preventing actions while travelling.
If you are stuck at this screen, the latest update might have broken your old savegame.
Press F4 two times to clear the old savegame and refresh this page. Warning: your progress will be reset. What can i do with this?
There should be option to closing window with stats after battle faster than clicking "ok" or option to attack one camp after another in queue or something
