I ask this because I played a AWI campaign through 1777, and Washington's Continental Army had swollen to 1532 power points. This force would NOT move, even though active, and when I tried to do so, the game crashed. Are there "break points" in number of units/power points for a given stack?
I'm thinking that I should have broken down this unwieldy stack into corps/divisions, Napoleonic-style, rather than putting the mass under one leader.
