Hello and thanks for the heads up on this. Growing pains is correct. We are almost done going through and cleaning these up. Please check your balance and see if it now back to normal.
This was a view bug (the coins were never moved) that resulted from the unconfirmed transactions earlier this week. Basically a bunch of pending transactions got added which were not processed yet but they were still affecting the balance calculation.
Did a major rewrite of it saturday and pushed it out, so this *should* be a thing of the past. Definitely made us look bad though as the balance is one thing that should never get messed up.
We are still going through support requests but if you see anything else definitely let us know. Thank you for bearing with us!
Nice to hear you guys are working on it.
I recommend letting the bitcoin daemon do it's magic and not store any user amounts in the database, that's why account feature exists.
https://en.bitcoin.it/wiki/Accounts_explainedYou could have avoided completely the double spending and account not synced issues by using the "account" feature of bitcoin an requiring at least 3 confirmations for the coins, if not 6 in your case by being a well known service.
