I have new stuff People!
While I was doing some research in CM:MS over the barriers for a reason I will tell later, When I was coming down from the heights to get nearer to the actual game area, I noticed this.
A Y-shape in the streets was noted back in October by myself, Apollo, and maybe Kenji and Enigma... but I don't think we ever posted about it.
This was down in the black area of D09. I think you found something bigger than that, in a different place.
In your (very nice!) picture, the center of the "Y" looks like it is positioned in the center of the Hub, where Districts 02,03,04,05,06, and 08 all join together. It also looks like you had District 03 loaded up, which leads me to deduce that you were jumping barriers up in D00 (which would be loaded too, and is not visible in your photo.)
Is this all correct? If I may ask, what out-of-map method did you use to get this photo?
