Just a hunch, but is that city Manaku connected to your internal trade network via the Sailing tech (e.g., trade along coast)? If so, that barbarian ship in your screenshots may be disrupting your trade routes and cutting off the resources needed to build the Rope Weavers Hut and the Hunters Camp. I believe Rope Weavers hut needs cloth or leather to be built, while Hunters Camp needs pelts I believe?
Good answer, but i am looking at why it isn't grayed out to begin with, rather than wasting time seeing it in the queue as buildable when it actually isnt?
