So I've been doing some tidying in my inbox, deleting labels and conversations of games that died, etcetera. Then I open up a few of the labels that I'd not tampered with, and find all the messages that had been sorted into them had vanished. I know they were there a day ago because I had gone through four of them to send a break-down of upcoming plot events to a partner. They are just gone, now. If it were just those four labels, I wouldn't mind as I have the PM I sent to my partner, but it wasn't just that one.
Are the messages still in my inbox, somewhere, should I not freak out?
Oh. I think they are still there, maybe. But they have scattered themselves through my other labels.
This is a very peculiar bug.
