Major When I make a backup to a course that have some lessons and try to restore this backup (in a new course, or merged into a another course), the structure of activities and resource was maked. The problem are into the content of lesson, the content has restored since a page that has program with absolute jump into lesson.
For example, in a backup lesson with 5 pages (brach1, branch2, branch3, branch4 and branch5) with the next configuration jumps: branch1->next page, branch2->next page, branch3->next page, branch4->next page|branch1, branch5->next page. When try to restore this lesson, I have a lesson with only 4 pages (branch1, branch2, branch3 and branch4), the process the restore lesson finish when found a page with a absolute jump.
