Description

Workaround:
Navigate to and open the newly-created level in the Content Browser prior to LaunchOn.

After using the Save Current As tool, Game runs into error when trying to LaunchOn. Editor displays a Warning about level not being fully loaded.

I encountered the following error during cook for LaunchOn to Windows:

CookResults:Warning: Warning Package /Game/New supposed to be fully loaded but isn't. RF_WasLoaded is set
LogCook:Warning: Package /Game/New supposed to be fully loaded but isn't. RF_WasLoaded is set
