Resource link issues when publishing Storyline courses to LMS or SCORM Cloud...

We have some courses that were completed recently as part of our company's compliance sequence.

The courses performed as designed when being developed and reviewed in Review 360, but for some reason, when we published the courses to our testing LMS and SCORM Cloud, 3 of the 5 courses generated error messages when we tested the links in the Resources section.

We were not able to resolve the issue and ended up having to recreate the 3 courses from a fresh template and adding the chapters from the original courses to them.

These courses have existed for 4 years and have undergone minor updates each year, so we're thinking the age and multiple updates may have caused some sort of corruption to the course files, but I'd be curious to hear if anyone else has experienced similar issues with their courses.

Thanks!
