Movement issues in casual games

I have noticed that if there is a unit next to a city i am attacking and I save the game and come back later, the stack attacks the unit next to the city rather than the city itself. This has happened many times. Also defensive lines don't always save properly.

Your moves will all go through as long as you don't hit 'save' after returning back to your game. There is a problem sometimes with loading the saved moves. So, if you return to your game and see that some of your moves are not there, it doesn't mean that they won't be processed _as long as you don't overwrite them_ by clicking 'save' again. Hope this all makes sense...
