I just had a user tell me that their course export, and subsequent import to a different course did not bring over any course files in spite of selecting the option to copy links and copies of the course files. I was able to replicate this. After the import the course files were completely empty. (I checked to make sure the permission thing was not the issue - the exporting/importing user must have permission to access the files in both the source and destination courses.).
Before I submit a ticket to Blackboard, has anyone else experienced this? Has there been a documented change in behavior that I failed to notice? I found nothing in the bug list. We are Q4 2016.
