I've quickly look at the codes. For all three proggies, user interfaces (vehicles.ui) are the same (checked with CRC32). However, the boolean %mydata.vehicle_profile.licensed and %mydata.vehicle_profile.list[current].use_extended are false for World and Basar. So a quick kludge is to remove them or set them to 1(true). But I do not know if this will solved it because the use_extended might be relevant (perhaps it's used to indicates the core codes that provides such function.) The "licensed" is not Truck Restrictions data (under About->Content) which is valid. It's the "Vehicle Profile" licensing which perhaps is not activate for proggy.
