One thing I just noticed when starting my layout - if you make a door at the top, the door appears at the bottom, too! (I think I avoided this by always not putting anything in any of the corners until now.)
So... If I put a door to Dinonykos's ward (for example), I also get a door in the other direction that I don't want (yet)... What to do?
(Anyway, I think my general order is: art, then text and quests
)
