Keep getting notifications for the same quote

I keep getting notifications that I've been quoted here: https://www.theforumsite.com/forum.php?p=4692725#4692725

It's told me like three times now, but only shows up once in my list and I've already viewed the thread multiple times

Ah I see mods are mere mortals after all

What the hell does mortality have to do with this?

No idea

uh ok

Anyway, since making this thread the notifications have stopped, but still - weird

This happens to me now and again. it was doing it earlier, but it appears to have stopped.
