Pausing the game while Ded. Server is on crashes UE4.6

While having a/the dedicated server enabled and trying to pause the game the entire Engine crashes.
Repro Steps:

  1. Create a Blueprint like this: http://i.imgur.com/x3llfYF.png (set game paused on key-press), compile it etc.
  2. Enable the “Run Dedicated Server” checkbox under the Play toolbar
  3. Click Play, press the defined key (or basically set the game as paused) and the engine crashes

Happens 10 out of 10 times. I’ve submitted 4 automatic crash reports.
Using UE4.6.
