On Xbox one, whenever I have London Commuter installed the game will either freeze or go to a black screen during the loading screens. In addition this issue occurs whenever more than 7 DLC's are installed, it makes it completely unplayable and is extremely frustrating as I own around 20 DLC and I have to install them individually to play any.
It’s rather a limitation of the Xbox you are using but I think either it needs high priority fixing or the routes that don’t work should never have been released on systems that clearly can’t cope Understandable if you can’t but I recommend moving to a series x as the most you usually get in terms of performance issues is a bit of a drop in frame rate at Victoria I would also recommend trying services that don’t go anywhere near major areas like Victoria such as the 166 if you wish to try the route out in the meantime
