Course completions in SCORM 1.2 with Storyline 2 courses

We have created and published several courses to SCORM 1.2 using SL2.   We report status to LMS as Completed/Failed and Track using quiz results page.  Until recently, if a student a exited a course while in the assessment prior to completing it, the LMS would report Completed-Failed.  Recently we have had issues when the student would exit a course while in the assessment, say after answering only 1 question, and the course would stay In-Progress.  Then after opening it again, and answering another question and exiting the assessment it Completes -Fails.  In fact in one instance, after answering only one question in the assessment and exiting the course the status was Completed-Passed.  Has there been any change to SL2 recently?  We have about 32 courses we've published and until recently we did not experience this issue.
