Can't build a galley

[Orcin]

I have two cities. Both have water access. My capital has a fishing quay on a navigable river, and it can make a galley. The second city has a fishing quay on a coastal tile. The quay tile is connected to the city center by other urban tiles, but the city center tile is not on the coast. The second city cannot build a galley because there is "no suitable location for the unit to spawn". The fishing quay in the second city is completely surrounded in the water by coastal reef tiles, none of which have been turned into rural tiles and some of which are not in the city's borders (but of course the quay is). Would any of that matter? Any other ideas why a galley cannot be built in this second city?

Do you already have a galley (or an enemy galley) on the fishing quay? Thats usually what it is for me.

This is weird.. I had that something similar happen to me when I was next to a lake.

This was it. There was an enemy galley on the quay tile that I had not noticed. Thanks!
