I was just trying to take a Xanax from my inventory. I had 2 in there which still show the purchase in my activity log. I did not move the Xanax which can be further verified by my log. I took one of the two and the screen started to loop like it was loading and got a 502 error. No energy or happy was apped yetthe Xanax was gone, no countdown timer or activity in my log. I refreshed my browser numerous times and there was still only 1 xanax remaining and no tracking of the Xanax going anywhere in the log. I took the second Xanax it once again did the loop like it was loading and i got a screen shot of it this time https://imgur.com/7aCOH4t and then got the 502 error and when returning back to inventory the second xanax was missing and still no activity in the log, no drug timer and no energy. https://imgur.com/P46bque.
I think the Auction House could use a little work. My suggestion would be for 2 new tabs. One would be an active bidding tab that shows auctions that you have bid on but not currently winning. The second tab would be for auctions you are currently winning. I find myself having to search through pages after getting an outbid notice to find and rebid. As the auction house has gotten more active since the fall with the cache items and new loot, that it's becoming hard to manage and find what you are looking for.
