After reviewing the auction, it started at Jan 31, 2019 6:12 Gmt +0 with 8m start bid from Darkvader as you can see.

Here you made a mistake, the remaining time left should be 1 hour 6 minutes instead of just 1 hour.

This should be the last highest bid posted at 6:03 GMT +0 by purplemauth.

So, the auction should ends at 6:12 GMT +0 and any bid after that should not be accepted. You posted the offer at 6:13 GMT +0 when the auction was already over and purplemauth should be announced as the winner.

I hope whatever I said is pretty clear and the winner of the auction is purplemauth. Please contact each other and finish the trade. Thanks.
