For some strange reason, a couple times today (and once yesterday) I tried to turn in a quest and I got an error saying I did not have the item(s). I knew I had them because I BOUGHT them within a minute earlier. I re-navigate to the quest giver, and apparently my quest was already turned in.

For one of the quests, I tried to buy from the pawn shop and I got the error that the item is no longer there. I know I was the one that bought it because it appeared in my inventory.

Also, I completed a new Shinwa quest in FOUR quests, not the usual five. And when I tried to withdraw wiz tokens (I did 1000 twice), I ended up withdrawing (no idea how) 3000 wiz tokens. My currency is displaying the correct amount after removing 3000 tokens.
