You can see on the blockchain https://steemd.com/steembay/@cryplectibles/steembay-auction-8-steem-monsters-fire-red-cards-3-commons-5-rares-no-reserve the user @mrviquez edited their comment and probably attempted to change their bid amount but the @steembay bot catches the actual first post.

Not sure if @SteemBay has something in mind when this occurs, as I have no doubts it can happen accidentally, but the system has to have something in place so people can't have accidental bids.

When I look on Steemdb I don't see the first error post though in that other users bid, but I'm not sure if I'm looking at this correctly

Is @SteemBay broke? You highest bid seems to have gone through fine though.
