Do route updates affect previous changes/additions?
I am planning to purchase the recent release of S8 Advance. JT have said to update the CML route or Aylesbury extension to allow all features of the S8 to function correctly. However, before the S8 was released, I regularly added bits and bobs to the CML route using JT assets only to further enhance the look of the route for my own personal use such as station furniture, buildings and extending certain tracks. Will the new update wipe out anything I've added to the route?
