An example of scaling issue: I created a new overland map, with a size of 5000×4000 or something. Then I use the landmass tool, default (polygon fractal). But when I zoom in on a coast (and not even a large zoom), the fractal isn't a fractal anymore, it's just a regular polygon, harsh and very much unnatural.

Since I want to create a whole world (or at least, a small continent), and be able later to zoom in specific region or kingdom or whatever, that doesn't work.

I'm probably messing something with metric and/or scaling, but I can't find what...
