Comment 12 for bug 1387801

> Ships returns to a port and unloads, but warehouse window gets into inconsistent state.

There is bug 1191556. Maybe related?

> Other alternative is that ship stays where it was and user will have to manuali click "cancel expedition".

Since the ship cannot do anything else, I consider this micro-management. Better send a message that there were problems and the ship will return to a port.

> If he instead continues with scouting and tries to build a port elsewhere, port is not finished and the ship is again in some inconsistent status.

I think such a case (unfinished port) is very difficult to handle, therefore I did not mention this option.
