I have had this same issue for several months now. It was somewhat the final straw that caused me to decide to use their wallet 0% to protect my BTC and to entirely use a deterministic wallet to store the BTC that I own/control (both for my hot wallet and cold storage)
Exactly this! People ditch blockchain.info or any other online wallet. Get Multibit or Electrum and you will be much safer and you won't ever again have this kind of problems.
Blockchain.info wallet has gone completely crazy lately. It's too buggy and even Bitcoin.org has delisted it from its list of official wallets.
