In this save game I experimented early with pioneers to claim resources in the influence area. I had noticed that some resources didn't show in the build box right away when the influence area absorbed them, since I had the tech I sent some pioneers to claim them.
The buildings all got constructed, some I did notice the effect. for instance the fire shard registered on the HUD, but at the town all there is, is a greyed out choice in the build box, showing that I could possibly build one. Also when I researched related techs I never got a option to build the structures (like the varying fire temples)
Towns and resources to show this:
Rashera - Mine
Laloona - Mill
Etox - Fire shard
Peeps - Gold Mine
This made me notice that there is no way (that I could find) to raze one of your own structures. I thought it might be a nice option for any unit to have the ability to raze a structure (friendly or not).
I also noticed in an Empire game that there were some related issues in a conquered town with the surrounding resources that were now supposedly mine. (I was doing my own version of an all-nighter and forgot to make a save on that game).
