Refreshing page causes bid to increase and user background does not save

As others have noted, if someone refreshes the page their bid is increased automatically to their max bid. This is not good!

Also there is a note when placing a bid that if the auction ends, the bid is increased to match the reserve (pic attached)?? This is not good behaviour for the buyer (the seller would love it I’m sure!).

Finally and a very small thing, if you choose a background to your profile picture from the options, none of them save.

The first two issues are stopping me from going to market to be honest. If a user experienced either of these it wouldn’t help gaining traction at all.

Thanks,
Peter
