Yeah, on my second runthrough there I found the sign. But it still doesn't help the fact that the building is hard to navigate. And actually I found that the layout makes a little more sense now compared to the exterior of the building, and it's not as big (comparatively) as I thought, but just some map notes or something would be good. If I have to run around a certain place enough to make me question OOC what the architect was thinking, then that leads to a loss of game immersion. I dunno, just a thought.
