As for the caps, I'll see and I can make the change (for once I get a feedback
), but it should be in the same style as for other layers: "surface" and "monde souterrain" in Balance mod. Sometimes less caps is better, when it's not a sentence. Those capitalized words will be seen on hover over a terrain hex, and as well under the minimap (layer's name). Perhaps "Ombremonde - steppes"?
To be honest I didn't know what "Exported Mod Files" is for, except that sometimes, I have to pick a new file from here. I move the feedback folder (mostly for Refineus's use) to the draft section then.
Hexed hexes: I retouched some screenshots for you to better see without a save. All selected hexes are the ones where units stop and forget their orders, that I am sure. I think this is because they are adjacent to a void hex, but one is adjacent to a SR "sacred forest" (dense vegetation) hex instead.
In the same folder, you'll find a save for this issue, and also to investigate about the bad linking to the ToW. I added screenshots before/after clicking on the link both in French and English, and it is still as I wrote: the first page of (Locations in) ToW is displayed for the selected language ("Académie..." in FR, "Abyssal.." in EN). It looks like it happens only for some sites, perhaps the SR versions of vanilla sites (Glass Furnace, Hallow Grove, Archon Fort are all okay for instance).
Last, you'll find screenshots of the page in ToW for Earth Altar and Eldritch Altar, so that you can see the difference.
