Thanks guille. Minefields have the "camo" trait as well as no zone of control, so I thought that they cannot be seen until triggered. I was unsure of the code timing. If the ship transport "disappears" before the minefield triggers, the attacking unit has nowhere to go. So I am now assuming the unit will bounce back onto the boat with a strength point missing.
I may plug a few into a scenario and see what happens.
Next question...
How do I delete "stations" left after removing a city on a rail line?
Leftover stations are driving me crazy. I place a city on a rail line. This generates a "station" overlay as well. I change my mind and move the city. The "station" stays behind and will not leave. The "stations" edit tab does NOT have an "empty" slot to delete stations, just more choices of different kinds. Right clicking deletes the station.... until I hit "generate tiles"(G) again. Then the b@stard is back again. I have tried removing the rail line as well... no dice. Tried using other overlays like tree clumps to get rid of them... nope.
Now don't get me wrong, I would love the little things if I could control them properly. I use LOTS of little froo-froo nick-nacks like that to make my maps immersive. They would make excellent farming hamlets, and will once I tame them. Since the vast majority of my city moves are one hex, I can choose a "station" that looks like suburbs and work around it in most cases, but it is annoying to lose control of my environment.
Any help be greatly appreciated. I did not free myself from Google Earth just to have some tiny wood-frame buildings constrain me.

EDIT - Writing it down made me think in another direction... and solved the problem!
Here is the solution for any who may follow. Delete everything in question(overlays, terrain, rails) and make lakes. Press G. Save it. Put it all back. Done. Whew.
New thread and alpha/mockup build will be ready for critique soon now. That was the last non-mod hurdle.
FURTHER EDIT - The damn things have been solved for sure now. The little f*^kers came back when I placed a city at a 3-way rail intersection.
Here is the rule. A city placed on any rail hex will form station(s) on ANY ADJOINING rail hex side. The stations are being formed on adjacent hexes! I was looking at wrong culprit.
To remove, just delete the city completely.
I am using the little "encampment" overlays in place of some city overlays, to simulate small towns with a rail station. These stations are screwing with my map tuning, but I know what to do now.
