This happens for me aswell, are you running on an original PS4? I'm thinking my original PS4 just can't handle the detail and extra AI services at Dresden.
Not only the normal PS4 but I’m on the Pro one and it crashes every time I approach Dresden that’s why from now I only do services from Dresden and not to
Really frustrating, hopefully it will be sorted by the next patch as it slightly spoils what IMO is a brilliant route.
