[Fixed] BUG - Unseen objects still harvestable/selectable

[Omega]

Objects on the first row can't be seen, yet can still be harvested and selected. Thus, I can click a blank spot at the upper corner of the map, and see it selects a tree. I can even harvest if that object is a resource.

yes, apparently the map "fades out" before it's supposed to, giving this odd appearance.

fixed, those tiles are now stripped of objects and the corresponding cells marked as untraversable in all fields (so no units walking or building there either).
