I got 20 patches that i can see, and they all turned from "normal randomized" ore to uranium and now stone. everything on the map (trees, rocks, ore deposit) are all turned to stone. I think it should atleast be random. even the patches of mixed resoures from tree to ore are all stone.
(this happend in about 3 hours.)
Although in resoures department i am unlucky as i got quarter / halfed and deplete random resource deposit as negatives and only player (temporary as positive) but that is still workable ...
