1) I have also observed choppy scrolling in the campaign map. I didn't see this in 1.3, it came back in 1.4, and remains in 1.5. It's most prevalent over North America, especially New France. I've changed all the video options availabe in-game from High to Low, different levels of Anti-Aliasing, turned shadows off, etc. and nothing affected the choppiness.

2) Several of the gold arrows used to show land-bridges between regions on the campaign map are gone. All are gone for the Lesser Antilles, but the one between Nova Scotia and mainland Canada is also gone. You can still walk units across each of these, it's just not made clear by the presense of the arrows in these places anymore.

3) The western regional border line for Cherokee Territory has wiggled well eastward, creating the visual appears of a neutral territory between Cherokee Territory and the region south of Michigan Territory. The apparent neutral zone is still owned by Cherrokee Territory, so the game knows who owns it, but the line on the map just needs to be put back.

4) Huron Territory can no longer export the Furs it produces. In the past, as GB, if I owned Huron Territory and Rupert's Land, all of Huron Territory's Fur appeared to be shipped out to Rupert's Land's harbor. In my current game, I own Rupert's Land AND New France (which has the only port connected by an actual road to the region capital of Huron Territory) and the Furs still are not being exported. I know something has changed, and I know that upgrading both trade ports mentioned does not allow the Furs to be exported, nor does improving the roads from Huron Territory to either Trade Port. So, I know something's changed, but I don't know what, or why, or whether the change seems logical.

5) The campaign map regional border lines between Michigan Territory and Upper Canada are still drawn incorrectly. I think this error has been in since 1.0. Upper Canada has a spit of land that juts west towards Michigan Territory. The map has a border line indicating that Michigan Territory owns the tip of that spit of land, but it doesn't, the entire spit is owned by Upper Canada.
