Same bug as reported Mar 11 '14 (except now also in empty levels), supposed to be resolved in 4.2.
Steps to reproduce:
- Create a new level
- Create a GameMode BP
- Hook up the GM’s ConstructionScript to the default print string action
- Set the World Settings Game Mode to the GameMode BP
- Press Play
- The ‘Hello’ statement will be printed twice
