Pressing "subfolder" creates the same sub-map, but with broken trails

[Kroolza]

Pressing "submap" creates the same sub-map, but with broken trails. In four out of five cases it is not created, and when it is created, the trails are incredibly thin and inconspicuous, there are no roads, and the sea routes are somehow visible and not broken

Steps to reproduce

1. Create a map, zoom in on a particular province with the mouse wheel
2. After zooming in, go to the menu and press "tools".
3. Then click on "subfolder" and make a sub-map, without changing the creation settings
4. Done! After that the routes are broken as I described above

Expected behavior
I was expecting to see a regular sub-map, but with clearly visible, major roads, trails, and sea lanes so I could save the sub-map and not use a magnifying glass

Hello. Submap is somehow experimental, I did not work on it and I assume it would required a full rework once other things are done. I don't believe I can put a fast fix now.

Hi. That's sad. Is there any other way to make the map more accurate so that the rivers are as beautiful as they are in the sub-map, and the banks look more realistic?

Only manually, I afraid.

I want to mention here that if there are two capitals present in the new submap, it will create a major route between them, starting the process of creating the minor routes. So try to get at least two capitals in the submap.
