Set down a White Wall (the tact spell) in the middle of a normal battlefield and try to spectate that fight. A good bunch of the map will look black to you (likely because the walls are opaque), meaning you can't click people that you can't see. If people are close enough to the walls, you can see them though - but the ones that are further down in this screenshot are not visible.

Isn't that still the same Issue about not being able to move your point of view, so you also can't join donut maps from castle dungeons? (outside of using commands)

Probably also still the same issue as if custom maps having opaque items scattered around. Would be really nice to have that fixed.
