This type of problem has been reported in previous betas, but I think this is the first time I've run into it. After moving all my units, the turn button did not turn green, and when I clicked on it nothing happened. I did notice there was an Altar unit which was stuck in the "running" animation, in case that has something to do with it. I'd forward a saved game, but of course reloading the game fixes the problem. With the reloaded game the Altar unit is no longer "running" in place, but is one tile removed from where it appeared when the game was stuck.
