Platform Xbox Series S. Account is linked to in game profile. Game is connected to the internet and says I am connected to Dovetail Live etc. I’ve been attempting to complete some of the tier one Mastery challenges on the Gospel Oak to Barking Riverside Overground route as the tier 2 reward sounds interesting. I chose to complete the 80mph challenge. At first I spawned in an HST and hit 80 but it didn’t register, so I assumed I’d have to use the route’s included train the 710. Managed to hit 80mph so saved game and exited. Still did not register in the mastery tier one tab. Tried again and it failed to register again. I’m not sure why such interesting additions would be hidden behind a broken unlocking system which is impossible to achieve.
I did the 80mph thing on PS5 the other day in the RHTT 66 loco move. Just crept over on the last downhill and registered ok on the Mastery progress, so it's only a bit broken, not fully broken. Got a gold medal too, somehow.
Somehow today it’s registering. Literally no idea why it’s started working but I’m not complaining. Cheers though.
