Xbox One lost content
My kid has been spending their Allowance since this game first came out. They have spent hours, upon hours, upon hours and so much of their own money, to buy 63 dlc packs. Almost every big pack there...

Don't worry, purchased content doesn't disappear completely, it may just need to be reinstalled but first of all they need to make sure that they are signed in to the right account on which the content was purchased. Then take a look at the attached links to get access to the content again.
Here are some troubleshooting steps with guidance on missing content:
If those don't help then since it's an Xbox account issue I'd recommend these Xbox support links here:
https://support.xbox.com/en-GB/help/games-apps/my-games-apps/view-downloadable-content
I can't say why it's vanished in the first place, that would usually only happen after a console reset, switching consoles without doing a network transfer or as I mentioned earlier by being signed in to the wrong account. But it will still be retrievable because they own it.
Good luck!
