In Patch 1.02 the map was altered in Minnesota. In the original map before the update it had St. Anthony as the city on the west bank of the Mississippi, and St. Paul as the City on the east bank.
In version 1.02 The city on the West bank is St. Paul, and the city on the East is Minneapolis.
Reverting the map back to how it was in the original version is correct, or Simply flip Minneapolis and St. Paul around.
Another note on Brigades. At the beginning of the game for the union reinforcements 3rd division 1st brigade is incorrect. It is listed as being the 5th & 11 Mass., 1st & 4th Michigan. It should be the 5 & 11th Mass., 1st Minn, 4th & 5th Penn.
And if you are looking for more elite units I suggest creating around June 1861 in Cincinnati the 9th Ohio & 2nd Minn under McCook. This elite brigade fought with distinction in Mill springs, Chickamauga, and Chattanooga. The 9th Ohio was an especially elite regiment they were nicknamed the "Dutch Devils" even though there was only 1 member of the regiment born in the Netherlands; a majority of the regiment was comprised of German veterans.
