I'm just coming to the final few days of the Space Race which was using trains from both Great Britain & Germany that I'd built up - so I was able to fulfil most single journeys with large amounts of materials (e.g. varying from 20 to 60).
At the same time, I reached level 40, and so USA opened up. I could see that I wasn't given any US locos for free and assumed I had to buy some, which I did (a couple of advanced, and one basic).
I then returned to the Space Race. All of a sudden, ONE of the four Space Race jobs will NOW only let me use a USA loco, so all of a sudden I find myself only being able to deliver 6 of something instead of at least five times that amount !
What gives ? And will the rest of the Space Race jobs start changing to only accept US locos ?
