I've noticed some American units that seem to be out of place in two scenarios, "We Hold These Truths" (1776) and "Forward from Valley Forge" (1783). I'm aware that some or all of these placements might be WAD: some might be cases of units out on campaign, but some appear to be misplaced garrisons.
I recall seeing something similar in some other scenarios (IIRC Savannah, GA garrison is listed as SC troops), but I haven't had time to look for them.
We Hold These Truths
--Montreal garrison is "2nd Massachusetts" militia
--NJ militia along with NY militia in New York city.
--CT militia along with NY militia in Albany, NY.
--"1st Delaware" militia are across the border in Fairfax, VA
--Two NC militia units are at Norfolk, Virginia with William Woodford
--Washington's army is in Massachusetts but contains a CT militia unit
--Maine militia is with Benedict Arnold in Quebec
Forward from Valley Forge
--"1st Rhode Island" militia in Providence, RI are classed as NY militia
--"2nd New Hampshire" militia is located in a town across the NY border. Skenesboro I think
--"2nd North Carolina" militia are located with Robert Howe in Camden, SC
