Quoting jlzignego, reply 1....snipped..... On a related note I can't seem to figure out how to stop units from "exploring" once I tell them to. I also couldn't disband the ship... not sure what is intended here or not.
I stopped my scouts from auto exploring by just clicking on them and giving them e new destination.
Mine (ships, scouts, heroes whoever) select new auto destinations after manually giving them a new destination. Like I said, I'm not sure if I'm running into a bug, an oversight, or something that is intentional.
