So this is just a wee bit irritating. I'm just about done with Heljarchen Hall; I'm totally done with the Main Hall, Cellar, and Entry sections, plus I even have all of the tiny annoying details put in (except for the ones I don't like), and I'm totally finished with the north and west wings. I can't add the east wing though--when I use the drafting table outside it's either blank or it brings up the blueprint for a Small House Layout (which I'm obviously done with...). I tried a Hail Mary and selected the Small House Layout and all it did was go blank again.

Anyone have a problem like this? Anyone know a way to work around it or fix it?
