In a recent game a certain city-state became angry with me, and from that point onward I could not enter the territory of the city-state, it showed it in red, just like trying to enter mountains or deep-ocean tiles in early game. This behavior persisted after the city-state returned to neutral state. It was never friends with me. I could enter the territories of other city-states just fine.

I've found this thread on civfanatics where a user encountered the exact same phenomena, but the participants there could not find any explanation.

Is it a bug? If it isn't, why does this happen, how can I prevent it, and can I restore the ability to move through that territory?

    I think I've seen this too. My money is on bug.

    Have you tried declaring war? It sounds like this uppity city-state deserves what's coming to it.

I and a handful of other people on the Civfanatics forums have seen this, but only with ships being unable to enter water tiles of a CS. It appears very rare and to be a bug with the game. None of us were able to determine a way to resolve this within the active game.
