Thank you very much for your answer. This transaction doesn't appear in the wallet I have for mysterious reason but the final sum is ok.
By any chance are you using Trust Wallet? I just noticed it happened the same to me: I received the payment, the sum is ok but it doesn't show up any incoming transfer, and actually I noticed that even last week's payment transaction now disappeared from the transactions history. Not sure if there is some bug in the app after the last update at this point... 
Great, at least my question seems less ridiculous after all and it may even be useful to others! Indeed this problem occurs on Trustwallet and I had never seen this before. This time I looked on the blockchain directly because the transaction didn't appear either, like the first time (And thanks Icopress!).
There is no desktop version for TW, there is just an extension otherwise.
