Yeah, this is something that even came up in my own testing, and I thought I addressed it, but I never tested the fix so it kinda don't always work due to a shenanigans of how it's configured. It should be properly fixed in the next version of the quest. (If you enter a dungeon and then exit it, it should take you back to where you expect yourself to be!)
As for level 7, it should have 10 entrances, two for the central area (one being a one-way pit drop into the middle of it), as well as 8 exterior branches. The map should be in the upper left corner branch, I believe.
