Allow sea unit production in swampy cities near coasts

[Islander]

I think it would make sense to allow Sea Serpents & Kraken to be produced in any city where they would be able to reach the sea.

An example is the map "High Seas Combat". I think the two swampy cities on the southern island should be able to produce sea creatures, since those cities can be attacked by sea creatures.

You can produce sea units in any city, even full desert cities and then if you wish vector them to a swamp/coastal city. Or has something changed?

Maze is right, it just gives you a nice little warning.
