Hi Community,
Thanks for letting us know about this. It does appear that something about the minor changes we implemented last night inadvertently made it so listings are being posted multiple times for some users. We are in the process of rolling back those changes now and this should no longer happen after that.
I will post again to this thread when this has been completed. We apologize for the trouble this has inevitably caused and we'll do our best to make sure this doesn't happen again.
