Question about movement at nearby fort.

[Nussbaum]

Hey there,

I'm new to Europa Universalis. I have run into a problem during a war and I was wondering if anyone could clear up the mechanics for me. I am called into a war by Denmark against Sweden. The Sweden had their troops on "Slaeland" (see screenshot), and I tried to move my troops from the country above Holstein to Fyn. However, when I did the game refused my movement command due to a nearby fort. As far I can see the only nearby fort present is the one owned by Denmark. Even though I don't think it would be needed, I also tried asking them for movement rights, but that didn't solve the problem.

Anyway, my question is why I can't move my troops to Fyn. I thought I understood the mechanics, but apparantly I don't. I play the vanila game.

From what I can tell from the screenshots it's a problem with the UI giving a false reason.
The reason you can't move to Fyn isn't because of a fort, but because of the hostile fleet blocking the way across the strait.

You can't go across straits if there are enemy ships in the same seazone.
