I too am having problems. It's taking much longer than normal to withdraw my btc. I have opened a support ticket and shall see if that helps.
All of the pending bitcoin withdrawal requests below 500 BTC were processed.
That's because we actually have three wallets, hot/warm/cold.
The simplified auditing procedure I used to refill the hot wallet only applies to the warm wallet.
I am working on the more extensive procedure for the cold storage wallet.
