you cannot send a unit to unrevealed territory.this should be possible, also if you do not know if it's possible to sail there (it maybe land). when encountering a coastline, the unit should stop then (abort the goto).
(same goes for land units, the opposite way).
This is a limitation of the path finding algorithm. Are you sure Col1 allowed it?
definitv yes, i am sure. see screenshots (with ship).
in the case above i had the luck to goto a location with ocean. if i get to high see (unknowingly), ship travels automatically to europe (i can't avoid it), if i goto a tile with land, ship stops at closest coast.
for land unit it's the opposite, they stop on land tile closest to selected goto-ocean tile.
OK, that is indeed definitive. To fix this will need some special case handling on the front of the path finding code. I think it can be fixed with a hack that just moves to the explored tile nearest the destination and then iterates, but the only way to be sure is to try it. However, I do not think this is a critical piece of functionality given it is easy for a player to work around, so I have moved this issue down the priority list a notch.
