Cornerstone LMS Issues

Hi all -We're experiencing some sporadic tracking/scoring issues with a number of Lectora-developed SCORM 1.2 titles that we are loading into our Cornerstone LMS. There are also a number of Lectora titles that are working properly.Here are a few of the symptoms, sorry these are vague, I am receiving these from a number of different sources within the company:- in one course, an end-user had the given correct answers in an assessment, but the course would not provide a completion variable to the LMS. However, another employee was able to pass through normally.- in another course, many people are being recorded as completed even if they answered assessment questions incorrectly and failed the mastery score- in one course, bookmarking is not working properly when resuming the courseI don't have much more information on the specifics of these at this time, as these titles were developed by other training people at our company. My hunch is that is either a problem with the publish settings in these Lectora titles, or that there are some strange Lectora->Cornerstone SCORM intercommunications going on. Has anyone had any experience with Cornerstone and Lectora that could shed some light on this?Thanks,Mark
