This has been the biggest disappointment in the whole FS22 modding community. It has been almost a year from the release now, the map is bugged like no other, there are no updates, there is no help from drmodding whatsoever. He doesn't care. Which is a shame because I can imagine that he put a lot of time into this, and it is a beautiful map otherwise.
But it is essentialy unplayable. Next time please just don't bother releasing a faulty map when you don't plan to provide any updates or help.
