Quick Question about the ranks.xml file, sorry if this has been asked before, I only took a quick scan through current comments.
When defining stations, vehicles etc. for each rank, are these absolute or cumulative? that is, is what is in the xml file for that given rank an explicit list of stations/vehicles available (i.e. will unlocks for a previous rank become unavailable if they aren't also present in a higher rank) or are the unlocks for the previous rank retained when ranking up? The documentation on the site didn't quite give me a solid answer on that
