Mon 27-1 7:36 I transferred 1.4 BTC from Mtgox... this never appeared in the blockchain.
at 7:40 I transferred the same amount. This instantly appeared in the blockchain and in my wallet.
Yesterday I made a support ticket. No answer yet

I'll keep u informed.
Can anyone with technical background explain what might be causing this error? Safety of the Bitcoin network is one of the main advantages of Bitcoin. Disappearing transactions is serious shit.
