Do I have to do the Scenarios of the Baby Bullet and the MP15DC for this Achivement. I've just finished all of the Base Game Scenarios on the Penninsula Corridor and thought I had to get this Achivement. Because on the Main-Spessart Bahn DLC, I got the "All MSB Scenario" Achivement without completing all the scenarios of the DB BR 204 Edit: OK. I got the Achivement after doing my last Scenario with the Baby Bullet. Really strange because I still had to do a Scenario with the MP15DC afterwards.
