The following applies to changes you make to inherited question banks, whether you make changes to them individually using the QBE or if you use Course Modules to make wholesale changes that affect inherited question banks.
If you install a CM that has a new version of a QB with the same name as a QB in the parent class, you permanently break the link to the parent class version of the QB. The same rule applies if you edit a parent question bank and then save/install it using the original name as the parent class.
If, in the future, you want to refresh the content of your class to match that in the parent class or restore the link to the parent class version of the content, you must save your new, edited QB under a different name and then delete the version that has the same (original) name as the original in the parent class' QB, or just delete the edited/modified version of the QB. The parent class will restore the matching (original) question bank automatically.
If you modify QBs or Assignments that you inherit from a shared parent class, there is no risk that the parent class version will overwrite your modified version, unless you specifically delete the modified QB or assignment from your child class. This means that if you make changes to the inherited QBs or assignments and save them to the original name, your changed versions sever the relationship with the parent asset and you will not receive any future updates from the parent class automatically. Therefore, you must stay in communication with the instructor in your shared parent class if you wish to be notified of changes to parent class Question Banks and Assignments.
Note that these behaviors do not affect assignments, which can carry duplicate names and therefore do not overwrite parent class assignments of the same name.
