I made a bid on a sword in the AH with 2 days remaining on it. The next day when I logged in, there were 3 days remaining on it. I think there's either a problem with the timer, or a way to reset the timer on an auction.
I'm going to try to screenshot all my AH purchases for a bit to see if I can replicate this. I was just wondering if anyone else has noticed. (Or maybe this has been discussed to death already.)
