White Western Star has disappeared off map after a multiplayer guest was transferring the truck over from Smithville Dam to Island Lake and their game crashed whilst in the loading screen. Now the truck and attached trailer(not winched) have disappeared and are not on either map or garage.
I also can’t buy the truck again because in the truck store it still says I need to discover the truck first even though it has been discovered (although the truck was discovered originally by a multiplayer guest, not the host)

Please help.
