Buildings that haven't been built yet shouldn't give any line-of-sight (LOS). At this moment planting buildings down gives LOS even though your not building it, this removes the need for scouts as you can just plop fake buildings "radar" around instead of scouting. Just reporting this, I didn't see it listed yet so sorry if I failed at searching.
