Sometime during my play yesterday my inventory lost over 100G. I didn't buy anything in the auction house yesterday afternoon, so my money didn't go there. I didn't mail it to anyone else. I didn't accidentally trade it. You can't "throw away" money. It just disappeared. This data is stored on the Blizzard databases, so my computer didn't "munge it up". The only thing that was unusual was I did have WoW crash once (while on a run in lower BRS), which has only happened like 2 or 3 times ever.
I requested an in-game support ticket (which of course, wasn't responded to while I was online), and when I logged back in today, I had two cut and paste messages in my in-game mailbox.
One was the "reminder" to "All subscribers" that "certain interface addons" could potentially install keyloggers. While not directly addressing my particular problem, some GM pulled this from his Support.txt file and pasted it to me, since it must have been the "closest" to my problem. The problem is that I run the game in wine under linux, and haven't seen any lingering wine processes laying about (and I would, since that's how it would work). It would be possible that an addon would capture my typing in the password, but addons don't get loaded until after you log in (for this very reason), so that's not an option.
The other in-game mail Blizzard sent me was that basic, "Sorry we couldn't address your problem while you were online, we sent you an email to your registered email address regarding this issue." I checked my email, no such message. I checked the logs on my mailserver (since I run my own mailserver) and there has been no such email coming through (yet).
So basically, Blizzard gave me the finger. :-\
While it's only 100G, and that's not catastrophic, it is still annoying that my issue wasn't even addressed. I just got cut-and-paste generic messages. This is the first support ticket I've ever opened since I started playing in February, but I guess it's just not important to Blizzard to actually respond to these sorts of tickets. I expect that Blizzard gets dozens if not hundreds of these a day, and their policy is probably to never affirmatively respond to "missing gold" reports, but it is still damn annoying.
