So I might not understand how auctions work and this probably isnÂ’t a bug but??

I dont know why the negitive days thing happens (someone else might) but the auctions end 1 minute after the time it says on the auction page (Example: if the auction ends at 5:00 HEE time itll go till 5:01 (please if im wrong someone correct me i don't want to give out incorrect info) but during that last minute people can sneak in a last minute bid... I personally dont ever leave the bid page at that point until I get the mail messages saying I won the horses at auction.
