Server Travel Causes Crash

Hi, I’ve been using Unreal Engine’s Blueprint Multiplayer Tutorials and got to episode 15 where we integrated launching the game. Doing this uses the command ‘servertravel’. For some reason, whenever I call server travel the game always crashes. I’ve attached an image to show what I’ve done. Also, I’ve checked the names and tried with other levels, and none of them work.

Thanks

Bump, anyone?
