Hello, I've noticed this problem first with TSW2 when trying to unlock "Be prepared" mastery that requires to prepare LMS Jubilee for service in timetable mode. At Lime Street at 7:00 you need to couple to wagons waiting at station. For some reason game does not register that you coupled locomotive to the wagons. Multiple times changed between lock type, between locked and unlocked, doing from camera view or in person - nothing helps. Animation shows that coupler is connected (including breaking pipes), but it still requires you to cuple to formation with 7 cars. I can uncouple the other locomotive and pull wagons, but task is still not considered complete. Happened at least twice with TSW2 and I just gave up, knowing that mastery is unreliable and won't register your achievement unless the stars are in correct position. Just decided to wait to for TSW3 with updated SOS route. But playing the TSW3 the same scenario got same result. At least mastery seems to work better. Started to play services involving Stanier and again one of them can't finish because coupling to formation is not considered done. So it is not just one specific service or one time occurance. Anyone else seeing problems with coupling in SOS? Or I just miss some non-obvious step. I am surprised that I do not see similar error reports in forums technical report section or on Google search. This is on Xbox Series X. If required I can add details about specific scenario numbers, but motivation to play SOS is low as there is high probability that all time spent will be wasted at the very last step.
