Just fixed a bug in a user story that's not actually part of the demo, but which is a critically useful element. Basically, you need to be able to download the physical hierarchy, edit it and re-upload it. It worked fine, but wound up double-booking each "moved" group. Fix was pretty trivial, but I made an error while doing the fix that meant it took close to an hour to find, track-down and fix the bug... hours are precious at this point.

Unfortunately, while rearranging the physical hierarchy now works on the dev machine, the blasted production server is still (basically randomly, it turns out) reporting that it has no connection to the database. I'm guessing it's a problem with the machine being CPU-starved or something like that, but that doesn't help with making it work for tomorrow.
