Bug 1:
You have a stack of units.
One of the units moves out of the stack.
Animation shows the unit walking out of the stack.
Move the second unit. It moves without animation (disappears and reappears in new square).
Bug 2: Take a unit in a city which has 2 more more move points.
Move it directly to a square 3 or more moves from the city.
The animation shows the unit walking on tiles that you would not pass through, it looks weird.
