Hi guys, I am trying to complete tier 1 of Mastery Challenge, I have done all of them, but "Spessart Freight Driver: Gain 5 levels on the BR 185.2" is not going up levels, its been stuck on level 1, I really want to unlock the diorama, but I can't because of this. Do you have any tips and suggestions about what I should do?? I have completed all scenarios 5/5 I have completed 211 of 309 services (but remember a lot of those services I haven't completed are the other trains on Main-Spessart Bahn). I have done all training for BR 185.2. I have taken a screenshot of what I mean Thanks everyone!
