Bug Threadlog saying I owe more replies than I actually do?

Yep, choosing "yes" to exit the thread will make it appear as though it is archived. I think the coding to get the counts to update as well is more complicated, so it's coming eventually but no ETA on that bit. It may be possible to have some kind of indicator that a thread is not yet archived even if you've exited it, but less in your face than the bold is -- I'll run it by the coding experts!
