if i drive a service or anything else the challenge counter remains to 0. oh, i have the Arosalinie, the LGV and the SEH but the game doesn't show their challenges. on the contrary, i don't have the CRR but it show me its challenges. i'm a bit confused
You will see all active mastery even for routes you don't have. Not all routes have mastery. Sometimes there is a delay on progress. Unfortunately there is not much you can do about that.
