Jusotra Fabricator Cruiser

Hi,

There is an error with the Fabricator Cruiser, it may have started after a save in my current game, I am not sure.

They worked fine in a previous game a few days ago. 

They are in control group 1 (my main fleet), the group is set to jump together, the control group they are a part of heads off and will jump without them, they just hang around wherever they are and a yellow line goes to another random planet nearby that I own. 

They do not follow the yellow line but it is always there when you click on them. 

As you can see, if I select them as a group on their own and tell them to go to a specific planet then they do, but they do not if told to do so as part of the larger group with other ships.
