I've got a bit of a problem, as the Union on Middle Difficulty I'm at chancellorville and I think I've broken the difficulty. At Shiloh I was extremely pressed but the past few major battles have been cakewalks other than Fredericks burg with my artillery and calvary just annihilating confederate troops till I'm getting minor battles done with casualties of about 500-1300 to 10,000 and individual 20 pndr parrots are racking up 10,000 kills in major battles. Is there a way to change the difficulty or do I need to restart. (And do Shiloh again....)
