2 bugs with the auction house

First off when you chose quality (common, uncommon, rare, very rare) in the dropdown list of crafting materials you always get the same list in the next dropdown list. So if you chose common you get Common Scraps, Assorted Fragments etc. in the next dropdown list. If you then search this is what the auctionhouse will find for you.
However if you chose uncommon quality you still get the same list of Common Scraps, Assorted Fragments etc. but when you search the auctionhouse will find the proper items for you (Subtle Essence, Shimmering Essence etc.).

The second bug is that the buyout button seems to be really unresponsive. I tried clicking it just once and waiting for a long time and nothing happened. Only when I spammed the button did I eventually get through. I repeated this several times. The last time I did it the auctionhouse ended up taking my money but never giving me the item I bought! I made sure I hadn't accidentally bid instead of buyout. My money was indeed 4000 lower but there was no item for me to collect I even checked back several hours later. Better fix this bug before people start using real money in this system!
