The supply system changed this mod completely, there's very few supply hubs. Especially in the north.

I know it's logical for there not to be good supply in a lot of areas, but the supply is so horrible it makes the game unplayable. I just did a campaign as the Boltons and it was impossible to push towards Winterfell because of the lack of supply. There's also huge supply problems by the Riverlands, I can't even imagine how bad it is in Essos for that matter.

One fix is obviously add more supply hubs, not only in cities but random tiles (dont over exaggerate). Also connecting more areas with railways (I like the focus where you connect the Dreadfort and Winterfell with a railway system. Also maybe upgrade the railways so the majority aren't lvl 1 everywhere.
