Sorry, I made a mistake. I counted 8 digits instead of 7 so I thought you were bypassing cache. My observation was wrong.

Really, I do not know what you are doing. I just wanted to make you think carefully about the "solution" you found. I mean that, if I were you, I would double check if I made some other small changes to the project in the meanwhile. Just to avoid facing again this problem without having fully understood it the first time.

I don't pretend to teach anything to anyone, neither to oblige someone to do something. Mine is just an advice from a guy that faces his own bugs everyday... some of them introduced by unlucky patches introduced to solve others!
