When you are editing SmartZones, and click on the "View other SmartZones" link in the upper right of the SmartZone listings, you get a "There are no other SmartZones in this account" error message or something to that effect.

Well, there ARE other SmartZones! You have to click on the SmartZones tab at the top to get to the others. This happened once before, and was fixed, but is now broken again.

At least they got the bug where you couldn't delete SmartZones fixed...that one only took 9 months to repair!
