Hi all, hope someone can help me please.
I'm part way through a game, it's going well, but I'm running into some issues constructing some buildings.
The image below shows a city I built in a particular position to try and keep free access to the lands south of here. I didn't want the red guy building a city there and isolating my southern empire. The city went down ok, but I cannot build anything there - the options are all greyed out. I have the required resources, but I can't even put down a workshop. Not sure why it's got a random city name above it - that's not the name I gave the city, but hey-ho.

It did occur to me that it might be a placement issue - perhaps I've got no-where to build because of the surrounding terrain?

Also, the fire shard to the west of Murkwood (see first picture) I cannot seem to build upon. I've got the required Shard Harvesting tech, but I can't seem to even click on the shard to build improvements (I checked the build option for the city to see if it was there, but it wasn't).

Any advice would be welcome!
