The Drunken Lizard Pub

Why in the areas around Talushorn do the roads not show on the map, regardless of the level of Cartography or using Reveal Map?

The map just shows a constant brown, when there are clear areas which appear to be roads. The few trees and other objects show on the map, and the clear areas near the water show as dark brown.

I've tried this with Cartography of 18, and also used Reveal Map at level 6.

Bug or feature?

I've noticed that, but I figured that in that area, the "roads" were really just where the taurexes had trampled the grass down. The only significant difference is that you can camp where it's been trampled and not where it's overgrown.

You also have a similar problem with walls in Westwillow near the Prospector. Some places just don't seem to be differentiated by cartography.

Dry ground has the same map color as road, which in turn has the same map color as some kinds of walls. It's the price of wanting to show ground detail effects with a limited palette, I'm afraid.
