ServerTravel MapName?game=GameMode called on client connected to a host triggers check(Ret != EBrowseReturnVal::Pending) when Nativized Blueprint is on

When game is built with Nativize Blueprint and the client who is connected to a host tries to server travel along with the host, a assert is hit.

1. Create new C++ Project
2. Add following to DefaultEngine.ini

   [/Script/Engine.GameEngine]
   +NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")
   
   [OnlineSubsystem]
   DefaultPlatformService=Steam
   
   [OnlineSubsystemSteam]
   bEnabled=true
   SteamDevAppId=480
   
   [/Script/OnlineSubsystemSteam.SteamNetDriver]
   NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"
   

3. Create two maps and save them
4. Follow attached Blueprint screenshot in Character Blueprint class
5. Build project as Windows 64bit and with Nativized Blueprints on.
6. Run built project on a separate computer
7. Press "J" to create session
8. Run Project through Visual Studio as Debug Client
9. Press "K" to join running session on separate computer
10. On separate computer, press "M" to server travel
11. On computer running Visual Studio, press "M" to server travel

RESULT:

Client hit assert when trying to use server travel:

 check(Ret != EBrowseReturnVal::Pending); // server travel should never create a pending net game

UnrealEngine.cpp : Line 9052

EXPECTED:

Client is able to server travel to host
