So i open the dlc, play the turtorial, go to start a route, and surprise, DTG added in the layers, suprised i open up a route from brighton, it is extremely laggy, i return to the menu and spawn at victoria, and my game crashed, I'm not sure if it is a bug or if the layers aren't supposed to be there, but this has to be fixed.
Hello, folks. This is a known issue (details here) and we will update on that thread when we know more. Thank you for your patience.
