Meaning: The plate system has a contact with a bounding plate system, and the bounding plate system may have a problem.

Recovery:

  1. Verify that the plate system has proper boundaries. Provide or update any missing boundaries as required.

  2. Recompute the bounding plate system.

  3. Recompute the object on the To Do List.
