Ever see something out of the corner of your eye, but when you turn it isn't there? That happened to me with the northern deep space border. When my camera was pointed far enough away from it, it was there. When I turned to look, it was gone. This didn't happen for the Delta Volanis border label. Maybe it's supposed to happen, and that sector is off limits? I'm not sure. I would attach photos, but it seems that the attach button is not there.

Oh yes, I noticed that too, thought it was just the (absolutely legal here) drugs I'm doing right now.
