Why do features in pak128 or other pakset lag behind pak64?
Prissi develops pak64, as well as being the head developer for the entire Simutrans project. Therefore, he is able to incorporate the latest features when a version of Simutrans is released. VS develops pak128, and has to wait for new features to be released before being able to incorporate them. Therefore, there can be a delay sometimes. Also pak sets are updated at variable speeds.
