Using autostrut on robotic hinges causes random ones to fail
If autostrut is set to heaviest part, this causes random hinges from the Breaking Ground DLC to fail to operate. The number of hinges effected varies from one scene load to the next, including the use of Return to Launch.
Setting autostrut to disabled allows th hinges to function correctly.
This video shows the manner in which they fail.
The included images show the change in which hinges are effected on successive uses of Return to Launch.
