I can also confirm that I have just completed a deposit of those coins back into the exchange where I made the withdrawal.
Still doesn't work for me

My MAPCs are still showing as unconfirmed, my wallet address still shows 0 on the blockchain and the transaction id still cannot be found on the blockchain. Again these are the coins I transferred to my wallet
before the blockchain was reset
OK, I don't know.
Could you backup your wallet.
