So I just completed SH02 Log Wagons To The Yard on RSN, as the scenario now seems to have been fixed. However, in the debrief noted although the AP correctly applied to the loco (363) progress, it was erroneously applied to DCZ as the route.
Just happened again yesterday evening. Did a Journey run on Maintalbahn where the 642 was substituted by a 612. At the end of the run, the AP was credited to the 612 correctly as the train, but the route AP added to Bremen to Oldenburg. This does need to be sorted!
Wonder if this is something that crept in with the last update? Sorry to tag DTG Alex but given the importance TSW places on AP and achievements including your most "popular" route and train this could do with investigating, please.
I've created a post here last week with the same issue, cross-check via ingame going to you profile if it really was counted wrong or just displayed wrong after a service https://forums.dovetailgames.com/threads/progress-for-srm-counts-against-bro.82240/
