Hi there, the rushing one I can tell you for certain is because you build low-production items, in a high-production city, the time it takes for it to be build is "capped" at 3 turns, so a minimum of 3 turns have to pass unless you rush it, then when the city build the hammers needed, and you look at rushing (or rushes at this point), you will actually receive Gildar, Pretty bugged if you ask me, several threads on this already.
Second one, Yea I saw this too, pretty silly, thanks for investigating further, hope it gets worked on.
Sincerely
