I find it annoying to explore an area, discover a shard/quest/resource, then leave that area and have the fog of war make it disappear. I mean, I saw it before and it's not like it's going away. Why doesn't it still show up on the 3d view and/or the cloth map? I shouldn't have to remember the locations of everything, especially on really big maps! I'm hoping this might just be a bug, but if not I'll file it as a suggestion.
