Okay...I've done a bit more testing on this and at least part of the strangeness I was seeing, that I reported in the forum on Saturday 11/12 seems to be tied to starting a second game without exiting to the desktop.
Problems with build items not appearing when they should and other wonkyness. It looks like some of the data that the game holds in memory isn't being cleared properly unless you exit the game all the way to the desktop.
