Xbox Series S Centro Regional Railways Class 323 Making Other Add Ons Inaccessible

When working through installing my add ons for TSW7, I've noticed that installing the Centro 323 causes other installed add ons to disappear from the game (they still show as installed on the console). Several routes disappear from the menus entirely while others are missing parts of the timetable unrelated to the 323 (for example Airedale-Wharfedale only showed the 'on foot' option). Uninstalling and reinstalling the 323 only changes which routes aren't appearing. The problem is resolved then the Centro 323 is uninstalled.

 

Luckily, it’s working again now. I’ve no idea what the problem was.
