Hi!
I'm playing the French and Indian War full campaign as the French against the AI, using the latest patch from here. It's summer 1758, and Montcalm has captured Albany. The British have received huge numbers of reinforcements and are already putting heavy pressure on my few troops. So far, so good - everything seems historically correct (except my conquest of Albany). But then a new British army appeared in New York and began the long march up the Hudson valley towards Albany. The said army is commanded by none other than Sir William Howe, the British C-in-C from the American War of Independence!
Howe did indeed take part in the French & Indian War, but he was only promoted to brigadier general after Wolfe's army conquered Quebec and he certainly wasn't an army commander during the war. His name doesn't even appear in the Leader document that lists all the commanders on both sides of the French and Indian War, so this must be a bug.
So maybe I should re-check Sir Billy's army for any Hessian regiments he may have brought with him from the future with his time machine...
