Missing Linkshell

A linkshell vanished from my in-game list, however I can still access its Lodestone forum, and others still see me online as a member in it.

The linkshell that vanished was one I had set at the time. It goes by the name Moogle Cake.

Pictures can explain it best.

So at this point it seems I can hear what's being said, but the icon indicating the linkshell is set isn't there in both log and menu. I input the line shown, and it didn't go through to any linkshell.

I'm still able to receive messages sent in Moogle Cake at this point.

From this point on, it's gone and I can't hear messages.

Apparently I'm still in the linkshell.

I don't know if it fixed with time, or required me to reboot my computer. Re-logging and restarting the game entirely didn't work for me earlier.
