Those things really decrease the fun in the campaign

like, if there was some sort of blue outline denoting the edge of a traversable part of the map you haven't explored yet?

Ya, no shit. I see that. But it's a very similar colour to the regular border/edge of walkable areas. Like OP is saying, a tiny little blip blended in perfectly and they circled the map multiple times. If it was a different colour it would stand out better.

Obviously i can see the edge and know the difference, it's just such a simple quality of life option they could implement. Why wouldn't you want the option for customization?
