If you're hosting Storyline content in a Moodle 1.x LMS, you may find that the course status is displayed as "suspended" even after users have completed it. This is related to a bug in Moodle 1.x (see MDL-19636).
Even though Moodle 1.x will incorrectly display the "suspended" designation for completed courses, it will properly record the user's score and completion in the attempt details.
This issue was resolved in Moodle version 2. To avoid this issue, you'll need to upgrade to Moodle 2.x.
