[Script API] Sandbox not starting issues. Preparing sandbox to start on game activity.

I am trying to get my sandbox up and running to do some prep for a game, but nothing I've tried has been working. how do you do "game activity"? I've tried both interacting as a GM and as a player on a second account and still have not had any success. 

I recommend launching your game in one tab and opening the Mod console in another tab. Once the game has launched, switch to the Mod console and restart the Sandbox.  Do any error messages appear? Can you share a screenshot here so we can help troubleshoot?  What game are you playing? What character sheet are you using? Jumpgate or Classic? Default or Experimental?
