To reproduce the problem :
1. Backup a cours containg SCORM
2. Restore it in another moodle platform (I did not try on the same moodle platform but I'm pretty sure it is the same)
3. Launch the scorm
4. The toc title is either wrong or just "TOC" and there are tracking problems with the first sco item
Causes I identified :
When restoring a scorm with the restore tool the launch field of the scorm table is not updated and still contains the source scorm first sco id. If a sco with that id exists, the toc title is this sco title, if not it is simply "TOC".
What I did by now :
To correct the data I have written a small php script to fixes launch fields of all scorm.
