Ah, I think I may know what this was. When a new random map is chosen, the server would set an invalid map for a split second (for internal reasons, another system would take that as a signal to do something and set a proper map again), and that invalid map may have been advertised. It only happened if there was a maps subdirectory on the server, that's why it slipped through debugging all of that time. There also were curious log messages I never was able to track down, but I fixed them now, and the invalid map advertising should stop.
