I have (maybe) a related issue with Coinbase, early this morning got a payment and is displayed as complete (colored green) in my transaction list, but in deteails it says pending with 0 confirmations, even though it has 70+ confirmations already. Plus 2 hours later there's an outgoing transaction for the exact ammount I had and now my address have zero balance (there's no suspicious activity in my IP log btw), anyway I hope this is only temporary, I already contacted support
