Here are 2 screenshot at turn2; the first is taken from version 2.0 and the second is taken from version1.0
In version2.0 the 90% of the AI controlled units have left their positions on turn2 (AI defending), while on the version1.0 only the 10% of the AI controlled units have left their position on turn2.
In both generated battles the turn limit was set to 2, so I quess that the difference between them (percentage of units moving) should be explained by the counter attack mechanism (maybe in a 2-turn battle all units are counter-attacking on turn1-2)
