Problem solved. Thank you very much, Limbic. (And happy anniversary!)

Not only did I have to pass the hash as a reference to the module function, I also had to get rid of that return $hash and the assignment which redefines the $hash (japhy pointed this out, but Limbic talked to me before and then I have been sitting on this comment for like an hour without creating it). Thanks all.
