Yes of course, it says on the news about the extra downloads for hill valley for the rest of the 0.2x series. Just thought the rails may come with the installation cos it's not in hill valley but it is part of it if you get what I mean?
If 0.2f was completed at an unspecified date at this time, if I downloaded the hill valley map with the rails, would the timetrain spawn on it at the beginning or would it still be on the mansion roof?
