I haven't had a chance to play much since the update.... One, thing I have noticed is all my add-on skins don't show up in the sim any more........ How do I get them to show up again?
With v1.50, all the vehicles classes have been changed, so I guess you have to edit your skins to get them back. Open the .veh files of each skin with notepad and change the class line. Here is a very handy chart between old and new classes.
