MyCoRe's update/delete system doesn't act very clever. Things that should done one time, are done multiple times over and over.
A user delete's a parent object with 500 children.
MyCoRe tries to delete the parent, but first, it has to delete all children.
MyCoRe runs through each child and deletes it.
BUT after the deletion of ONE child, the parent object will be updated.
This results in updating the parent 500 times, before its actually deleted.
