I believe this is the problem in the code . No string was added for the new transport
if (args.Count < 1) Msg("helpBuy", player, new object[] {
_itemsNeededToBuyVehicles, GetVehicleSettings(RowBoatPrefab).price.ToString(), GetVehicleSettings(RhibPrefab).price.ToString(),
GetVehicleSettings(SedanPrefab).price.ToString(), GetVehicleSettings(HotAirBalloonPrefab).price.ToString(), GetVehicleSettings(MiniCopterPrefab).price.ToString(),
GetVehicleSettings(ChinookPrefab).price.ToString()
if (args.Count < 1) Msg("helpBuy", player, new object[] {
_itemsNeededToBuyVehicles, GetVehicleSettings(RowBoatPrefab).price.ToString(), GetVehicleSettings(RhibPrefab).price.ToString(),
GetVehicleSettings(SedanPrefab).price.ToString(), GetVehicleSettings(HotAirBalloonPrefab).price.ToString(), GetVehicleSettings(MiniCopterPrefab).price.ToString(),
GetVehicleSettings(ChinookPrefab).price.ToString()
