I'm on 68 out of 80 distance for the island line 2022 mastery. After that I did two timetables and a scenario and it doesn't register the distance anymore. Anybody else experience this?..Is there a solution?
The only solution is to just keep driving and not worry about Mastery. Eventually it will be unlocked and you will be rewarded with a non-existent out-of-service 483. The overlay to activate it is simply missing.
