Anyone use the explore option - with land and/or sea units? I don't usually use them on land, but I will use them at sea - to chart the map mostly. Funny thing happened on my recent game. I'm at war with the Zulu. They got to my continent via sea travel first and before I was able to build any sort of a navy. They dropped a settler on a teeny peice of land between to coastal cities (which would have overlapped one of my cities) - so I plugged them before they could settle and took the two workers from the settler. At war, no big deal. A turn or two later, I send a few vessles out to start charting and when one of the vessles finds an enemy ship in the black, it stops right next to it, unprovoked and is activated for a manual intervention. It's like it knew that I wanted to blast that enemy ship and didn't continue on with the explore pattern. Man, that was cool - I popped that ship and put it back on explore. I didn't realize that the explore function automatically breaks in mid-course if it stumbles upon an enemy ship.
