Hi, everyone!

For about a year now, one of my friends has had an issue with linkshells. Every time we try to add him to one, we get the message that the person "cannot be invited to anymore linkshells." For some reason, the game thinks he's maxed on LSs. GMs haven't helped, so I'm asking here if anyone else has had this glitch happen and how to resolve it.

GMs advised him to delete all his linkshells to try resetting his list, but that didn't work.
He's also reinstalled the game, that also didn't work.

Any other advice? We'd greatly appreciate it.
