This has happened to me today. Fortunately it happened to a character that only had 5g on it at the time.
The odd thing about this is that it's literally *only gold* that is missing... I still have the silver and copper amounts... just the gold is missing.
This gold loss has to be traceable and restorable. Database write errors aren't terribly hard to find when they occur, so it boggles my mind that the ToS would say it's not restorable. :\
I'm not really bothered about 5 gold, but this gives me grave concerns about this happening again... 6 months from now, on a character I could have hundreds, or thousands of gold on.
That's the kind of thing that makes people quit.
