Doctor Archive

I've checked the Planetary Map and i can see that a * indicates a Doc is in that location and a half moon means there is no doc at that location. Ok, I've been to half a dozen hospitals with the * and there is no doctor at these locations. Is this a bug?

Yes. There is a bug that causes a hospital to show up as manned if a doc registers in it, then logs out in it without first walking outside to cancel the registration.
