Production adjustment fix

* The production adjustment function was completely off (and always has

* The problem with the adjustment function not being reported means that
no-one ever encountered it. As a consequence, happiness strike threshold
has been increased to 50%

/!\ Full database reset required (or at least much easier than other
options).
