You may receive an "Error downloading scripts for campaign" message in your API console if you were trying to run a game in the last few hours as of this post. If so, just re-save and it should fix the problem. There was a network issue for a little while tonight that interfered with (among other things) the ability of the API servers to communicate with our main App server (which is necessary to download scripts when the campaign starts up). Sorry for the inconvenience!
