@DarthJobbie I appreciate you advocating for your guildmate, but I think at this point you need to reduce the number of posts and be sure you're not hijacking other threads. The developer tracker is here: https://trello.com/b/vgQhKHMf/swgoh-developer-tracker. You can keep checking that, but there's no telling how long a bug will take to fix. If the error code 9 issue is under investigation, then all you can do is wait. I believe your guildmate may be suffering from a singular issue affecting several other users who have been posting lately. If my hunch is correct (and it is just a hunch, as I do not work for CG and do not have access to the game files), then there is a possibility your friend's mods might be restored if they fix this issue. Bug again, I can't actually speak to that.
As for the person who told you he sold them, it sounds like that might have been a response from EA general Support. Unfortunately, that resource is outsourced and any given service member may not have accurate knowledge of this game in particular. Since the issue has now been reported on Answers HQ,however, actual members of the development team are now aware of these issues and are looking into it.
