[SPOILER] Brennenburg Castle's overall layout (complete map)

[Bridge]

All the maps come from hidethedecay on deviantart. The individual maps are much more useful if you're actually trying to play through the game:

As you mentioned, with the elevator room flipped, the prison areas are directly beneath the back hall and the study/guest room area, so it's impossible to distinguish. I might upload another version with just the essential rooms tonight.

Yeah but I mean because it seems like you have already connected them all, it should just be as simple as hiding the other layer folders (assuming that's how you've got it set up) and then release 3-4 separate maps of the connected areas.
