This issue is still occuring for me, even after the auction was no longer listed I never recieved my ebs OR a message from the game saying that the auction had ended. I had around 22 horses in the auction, only 2 without bids (Would be set free automatically if not bidded on) When I go to the 'Auction Home' there are no auctions of mine currently running either.

Also..I did not get any of my horses back, all of them were either send to their new owners, set free, or somewhere else...?

It's happening on another one.

And again just now.
