Hi, first of all thanks for the insanely good mod.
Secondly, I have now after 50h playtime noticed that on my map apparently no Imersite spawns. I use RSO 6.2.0 and the latest 1.1 builds of factorio and Krastorio 2. I have disabled cliffs in map generation.
As a test I generated a new map with cliffs. There I set the richness of imersite to max and quickly found imersite via the map editor.
But in the map editor I could not find imersite in my 50h save.
Is Imersite simply generated so extremely rarely with the default values that you really have to go out extremely far (>15 minutes by car) or is Imersite simply not generated when cliffs are disabled.
