Just wanted to make a quick PSA, as I had real trouble with the Mastery for Island Line 2022 recently and it seems as though its been a running theme. Some things I discovered: Tier 1: I found that only some scenarios actually counted for this. In my experience only ''Brading Rescue'' and ''Blow me Away'' worked. However the tutorials do seem to be working for this step, so maybe that's the way to go here. The walking milestone for Tier 1 seemed to work fine. Tier 2: Similar to Tier 1, only some scenarios seemed to actually count towards the total - but weirdly not the same ones as before. For Tier 2, ''Brading Rescue'' still worked for me, but not ''Blow me away''. However ''Sea Transport Service'' did work this time. The Milage challenge for the second part of Tier 2 was a bit more complicated. In a similar way to scenarios only some timetabled services seemed to register. The following services worked for me 2U10-B: 07:15 2D13: 08:45 2D37-B_02: 15:18 Unfortunately it was just a case of repeating these and checking to see if it was registering. There were probably a lot more that would have registered and I can safely say there were definitely some that did not - but these are the ones I tried and stuck with. Obviously this might not be the same for everyone - the mastery system is pretty fickle, sometimes showing different results just by reloading the mastery screen! I just wanted to share my experience anyway in case it helps someone Thanks!
