Technically, I had made several rooms, so I would think at least ONE of them should have been a full room. At any rate, the problem is moot now; it was fixed with the update. 

Hello, sorry to be a bother, but I am experiencing a bizarre glitch since the latest patch. When clicking on a build mode object in the catalog, the details it pulls up have a blank space where the larger picture should be, the word "moodlet" under it, and no color/design options. Buy mode objects display normally. In addition, some newly-placed walls (2nd story and above, 1st story functioned normally) appeared blue and would only show as "up" or "down", not cutaway.

I have removed every speck of custom content from my game except for Awesomemod to no avail; only when I removed Awesomemod did the objects display normally. I tested Awesomemod alone in a new town after deleting all caches but still found the bug.

edit: after additional testing, I found that using the config tool to disable improved object information allows build objects to function normally. However, prior to the recent update, that feature worked fine.
