Im a little rusty: does an embassy of a conquered City State provide a vote in the world congress? I think not, as the CS stops behaving like one once is conquered, but just to make sure. Thanks a lot
It is possible to capture a neighboring CS embassy tile with the help of a Great General. After that, you can put your embassy and get a vote for Congress.
I don't know if the voice of the owner of the previous embassy is being deleted.
