@Tony - Sure, that's not the word I would use either, but I think it's pretty clear that's what he's talking about. New patch, adds a new set of buildings, they look different. He probably started a new city on one of the European maps without knowing about the patch and was surprised at the new buildings.

I would assume he's asking about the new European themed buildings that came in the latest major patch.

Is there any part of your water connection where the water has dried up? Perhaps where there are a lot of water pumps sucking it all up? A recently built dam?

What I think it would be good to know is the traffic flow on the bridge with the yellow line across it. Could it be that that is your bottleneck? It definitely looks like everyone in your first screenshot is trying to turn right. Are they trying to get across that bridge? Also, I can't really tell from your second image, are there any exits off the highway and into your Holly Heights district?

Yes, it appears the tooltips for monument unlocks are currently bugged and not updating to show what you actually need to build.

Right, and the host just wandering around the desert and dying is easily explained as the AI being too shortsighted to realize that it wants to attack a target it can't reach. It wants to do a thing, so it does a thing and screw whether it can actually achieve that thing or not. Unfortunately because of how complicated this game is, without having the exact game state to look at it will be very difficult to provide an answer to this question.

As far as I'm aware though host invasions are not a plot, simply an event. In fact, when an NPC decides to start a host invasion, the game explicitly gives the target 2 years notice. Musa here's only concern as far as spymasters related to the host invasion would be his target's spymaster trying to raise plot power to assassinate him.

Could we maybe get a screenshot of this guy? It would help a lot to know his stats/traits/claims etc.
