Comment 22 for bug 1234725

I think the stripes are too noisy. Maybe just matching the color with the port space as suggested by the original mockup would be best after all?

If you look closely at the saveegame, if you build another military building that will conquer a bit of Sea close to the port space, the port space will pop into view. So the issue here is not that the port space is concealed by anything on land, like roads, other buildings or trees.

This is the experiment that I did: add some more water to the map, add some port spaces, remove the water. The port space will disappear. Without the buildcap check, as soon as you build something that partially covers the port space, suddenly the medium size and small size buildhelp icons will turn blue around the impossible port space that would never be shown as a port space and where you will never be able to build a port. This is unexpected behaviour and will completely confuse payers.

So, the new icons do the exact same check as the port space does. Changing that behavior has potential for new bugs. It would be nice to still get this feature into Build 19 (while we're still stuck with the desync), but fiddling with the buildcaps isn't really something that we should do at this point.
