Strange I checked my subscribed workshop routes nothing showing updated today, I wonder what as updated I guess just have to wait for DTG Jamie to replay back.
I just saw a post in the the Riesa Dresden topic, where someone asked about what was in an update today. Do you have that route? It must have been a route specific update, as I'm still on the same core.
Seems like updates for specific routes so only some would get it. No mention on Steam of any updates. When I get an update and don't know what it was I open Windows File Explorer go to my Railworks folder and then open that and select the date modified. You can open any folder to check which in the case of a route is usually the contents folder.
BTW, update information gets posted to the Steam discussion thread stickied there. But for some reason, not on the official forum. Funny, that is.
