Negative Bitcoins?

[deus-ex-machina]

Just withdrew my winnings from Dragon's Tale. My wallet now shows a negative balance of exactly what I withdrew. I looked at the blockchain and it seems all of it was sent back in little chunks. I tried logging into Dragon's Tale to tell the game's admin, but was greeted with an error stating I was already logged in. Can I get any help with this? I'd be willing to talk through PM with someone who works with the game if I need to.

On a related note, I have noticed two posts from my account on the game's thread. I did not make either post. I have changed my password since, but I would like those posts removed, as I cannot seem to do so.

It should be noted that I am merely wondering what happened. I am not blaming anyone and I do not consider the game or its admins at fault. I thought I should say this because it seems to be assumed every time I encounter a bug in something.

Your wallet in-game or your actual BTC wallet? AFAIK, it's impossible to have a negative balance in Bitcoin. Are you comfortable posting the address you withdrew to?
