Can someone tell me if my sync are lost forever?  I attempted to send some sync from my mac wallet earlier today to bittrex but i did not realize until a few hours later that I was using an older mac wallet (downloaded 3 weeks ago).  After contacting bittrex they pointed out that the txid isn't in the blockchain, which I checked the explorer and its not there.   And now after updating to mac wallet v1.0.4.0 its stuck synchronizing on block 94391.  the wallet transaction details has it confirmed: Status 184 confirmations.  Did I just lose 1 sync? Any help would be appreciated.
