After finishing the main game, I'm in the first set of after game battlefields. I have completed all 3 levels of 2 dungeons, but in the 1st level of the 3rd dungeon I can't find a door that will give me access to the rest of the dungeon. There are some of those "decorations" at the top of the wall that are there for other doors you can pass through, but there is no door there. I've tried clicking outside the trapped area on both the minimap and the dungeon, but no green marker appears as it does in areas you can access. I'm not talking about portals to lower levels. All this is on the same level. Is this to be expected in some after game dungeons, or is this a bug?
