I can't tell if there's an issue on a system level, because Launchpad never restores my app organization every time I restore from a backup. It's such a pain to reorganize the apps and put into folders, especially when adding to a folder gets so janky. I have to match my organization with my other Mac as well for consistency.
Does it restore for you or do you have to start all over again?
