And other lights for that matter - they seem to take up a huge amount more space in the game than they actually show. I am guessing it has something to do with the way flash recognizes the radius of the light. But it means that in the rooms in my tower with ceiling lights, I can't get into the SDBs that are under those lights to collect currants, I have to move them out of the way first.
Seems surprising that no one else has reported this, but I searched for this one but didn't find it. Hope I'm not doing a duplicate post.
