If you attack a city with no roads, and that city has a landship, and you capture said landship, and then retreat, the game gets stuck. The game won't let you continue until you tell the landship where to go, and it can't go anywhere.
Indeed, good point! This shall be fixed. Probably by removing the landship, but eh. :D

Hopefully we get the full value of the landship back on removal?
Well you've basically abandoned the landship in order to retreat. Unless by we you mean the owner of the city you've retreated from?
Owner of the vehicle. (i doubt any players would be silly enough to do this unless they have made some sort of mobile defense installation, plus the AI probably needs the extra $)
