I have a game in 1.1 where when I click next turn, nothing happens. I was building a new city right before this happened.
I also noticed an oddity in the game where a unit I designed shows up twice. I had noticed earlier that the unit's portrait had gotten changed to the portrait of another unit I built so I went in to fix it. After this, the unit shows up twice.
Here's the save file:

Hope this helps a little.
