A thread I never flagged

Yeah, it's a glitch. I have only flagged one or two threads ever and I've got a whole list of things I allegedly flagged.

I've also got "friends" listed who never picked me, and "foes" I've never met or posted on a thread with for some reason.

Doesn't seem to have hurt anything, though, but I sympathize; it's very mildly annoying.

ATS is coded pretty tightly for as big as it is, imo.

Take 'er easy and don't sweat it.

"ATS is like a box of chocolates, you never know what you're gonna' get."

I've learned to let the minor glitches just happen and go on. I don't understand much about all the coding, but it must be a heck of a job for a site as diverse and large as this one. I'm surprised there aren't more glitches.

At least you can see what you haven't flagged

That's scary stuff...

"ATS is like a box of chocolates, you never know what you're gonna' get."

ATS should adopt this as its official slogan.
And if not, I am adopting it.

Thanks to everyone for the replies.

(And I would still like to know what's causing it. )
