Ship won't launch.

I go to take off and the game freezes after she ship leaves the map and stays stuck on the map I am leaving. Any help would be appreciated greatly as I'd really not like to start over. However if someone can identify the mod that is causing it so I can delete it. SO BE IT.

This is the error I am getting no matter what save I do it on:

System.NullReferenceException: Object reference not set to an instance of an object
