i still possess balance in my account, if you sent out two transactions same size as they came in, how can i have funds in my account?

this whole thing dont add up. please look further, i will tip you if you put in effort in trying to locate the coins.

I can show the deposit and withdraw transactions of this account. We received two deposits and two withdrawals of the same size were made. If your bitcoin client can't see them, maybe it's not handling malleability attacks correctly?

Do you mean that your account could deposit and withdraw the balance, but it never showed up as credited on Satoshi Dice?

I am checking the actual balance credited to the accounts from deposits and it all adds up. The deposit and withdrawal transactions are in the blockchain for anyone to view and we sent out the same amount of coins that we received.

Why you credited on 2.39 BTC more after you lost 18 BTC deposit? Can you make screenshots of the site?

I see the account with the transfers you refer to (hash bf59655914a36be27dff469c9f8c35de). It was credited 20.89834359 in total and the same amount show as withdrawn. It also has two deposits and two withdrawals.

Your other account (hash 4c85007005c2bc15a666eb21febca871) has similar deposits and withdrawals that both add up and were credited.

I can see two deposits and two withdrawals in your account and they were all processed properly. Your account was probably among the accounts that had unconfirmed balance shown from the malleability attack that was going on a while back. We have flushed these duplicate transactions that never confirmed.

The malleability attack was affecting seemingly random transactions on the bitcoin network by broadcasting duplicate transactions with a different transaction id. Our bitcoin software saw both the original transactions and the duplicates and added these as unconfirmed balance. However only the ones that confirmed were credited to accounts. Our software didn't handle this properly and left the unconfirmed balance from the transactions that never confirmed. So the accounts with deposits that were affected by the malleability attack were properly credited once one of the transactions confirmed, but kept showing also the unconfirmed balance from the duplicate transaction. We have now implemented error handing for this so that once our bitcoin software realises that a transaction will never confirm, it no longer shows it as unconfirmed balance. However, all accounts were always credited correctly when we received confirmations.

The malleability attack also affected some withdrawals. We remove the user balance immediately when a withdrawal is made and broadcast the transaction. If the transaction is attacked with the malleability attack, our software will see the duplicate transaction and subtract the balance from the account a second time. This balance remains subtracted when having zero confirmations but we have now corrected so that when our software realises that a duplicate transaction will never confirm, the user balance goes back to normal. We have also corrected the displayed balance on all affected accounts.

Please resubmit your email and I check it right away!

when was the site down? i can log in fine.

As I mentioned, I've been sending emails every week since four weeks ago, but with no answer at all from them. Also in all this time they haven't checked this thread, as I suppose they could answer here too.

Yeah, I did send with many outputs.

In my case it's been more or less one month since I deposited. It has shown as "waiting for confirmation" (even though it had many confirmations on the blockchain) for all this time but today it simply shows 0 balance and 0 unconfirmed.

I have sent 4 emails; more or less one per week with no answer. And for what I see in this thread it's happening fairly often (especially the "no answer from support" part).

an update when it's done and what was the error is always appreciated

No you shouldn't give secret link to anyone, just wait for support to reply.
