Transactions dissapperar from blockchain.info

[spunit262]

About a week ago I requested payout form coidad.com and within a day I saw the payout on blockchain.info but not my local wallet (MultiBit). Then two days ago (the 8th) I say the payout again as new tx on blockchain.info but not my local wallet, but I could not find any evidence of the one from a week ago. Then yesterday I look at my address on blockchain.info and the tx from just the day before wasn't there ether.

Is it normal for blockchain.info to forget about unconfirmed transaction, especially one that's not even a day old? Or am I just going crazy?
