I have a problem with colonization. Everything worked perfect, while colonizing Canada region with Scandinavia, but when I tried to go on the next region(New Louisiana) I could only colonize 3 territory, and after that, it says that the closest core with a port is Stockholm(2000 range away). I think I should be able to colonize next to my core territory.

On the screenshot, on the north side(Vinland) is my colonial nation, the selected province is my core, and I can't continue to colonize Minnesota for example.
