After the down time the prices of elixirs dropped. I remember that they were bought by the staff and then their shop prices were increased not too long ago, but it looks like that has been undone.
(It's quite unfortunate for me, since I just spent a fortune right before the down time buying a lot of elixirs to pawn them over time. But this is also why I noticed the change in the first place.)
pretty much all items in all shops had their prices lowered...like the jewelry in All That Glitters, for example...
Looks like the price on everything was reset. SBQ too.

Does this count as a bug? I've been hoarding all the books I can find...
The prices should be back to the range that they were. If you got anything during the problem time, you can keep it. :)
When I look for the prices of some of the elixirs that I got and hover over the item it still says a very low "Official Price" for most of them. I know they should be higher, bc every one I bought would be worth at least 10k more when I would pawn them. Now some of the prices are still only 2 or 3k...
