Question For A Mapbuilder.

I played around with the camera a bit while driving and i found this under East Croydon on London Commuter

I am curious and I would like to know what that is?




I've accidentally landed under the map a few times, no big deal, but I've never seen anything like this.

 

Two more pictures of this Cube.

 

The drawing of gigantic unseen whatnots isn’t going to be doing the performance any favours, whatever it is.

 

Yeah but I reckon if they delete it, something really bad will happen to the above rails world.

 

Out of curiosity, I looked up other lag locations in the Game. Dresden Mitte and London Victoria.
Nothing extraordinary in Dresden Mitte but there is something strange in Victoria.

DD-Mitte

L-Victoria
