Seamless travel not supported in single process warning while single process PIE is disabled

I initially noticed this when I had it set to a single process, but the same error was occurring when I had single process turned off.

To double check that Seamless travel was enabled I ran the console command "displayall GameMode bUseSeamlessTravel". Since it was enabled I was expecting to travel to the map I was on (restart essentialy). I tried this travel with both Highrise and Sanctuary.

Repro:

1. Create ShooterGame project from the launcher and open UE4Editor
2. In project browser select the created project.
3. Select the drop down arrow next to the Play button in the tool bar
4. Change the number of players to 2
5. Open the Play Advanced Settings
6. Under multiplayer options uncheck Use Single Process
7. Change Editor Multiplayer Mode to Play As Listen Server
8. Close the Advanced Settings and PIE
9. Press ~ in the viewport and enter the command "ServerTravel Highrise"

Result:
Server travel does not occur and "LogWorld:Warning:ServerTravel: Seamless travel currently NOT supported in single process PIE" appears in output log.

Expect:
Server and client travel to the Highrise map

Frequency:
100%
