Servertravel + physics vehicle = assert

Hi guys,

Seems that it’s not possible to make a map switch using the “servertravel” command when in the level there is a physics vehicle.

This is the assert that is triggered if you run the command:

Assertion failed: Vehicle != NULL
[File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.2\Engine\Source\Runtime\Engine\Private\Vehicles\PhysXVehicleManager.cpp]
[Line: 218]

How to reproduce:

  1. open the VEHICLE GAME
  2. Create an empty map and save it as empty.umap in the Maps folder
  3. Open AVehicleGameMode.cpp and in the constructor put “bUseSeamlessTravel = true;
  4. Compile
  5. Play the game with 2 clients
  6. Type in the console “servertravel empty

thanks in advance,
Martino
