Pathfinder
you should have saved it for me to look at. the hack is far more stable than that - 99% of cases where something bizarre like that happens its because A) your settings were too radical and you didnt realize it or B) you enabled the post award system for users who would abuse it..
there are only maybe 2 earning bugs in 1.4rc1 (which i have patches for btw) and both have to do with LOSING credits.
even if it was a settings problem, after i looked it over and corrected them - a quick run of the mass credit updater would have set you back on your feet
besides, im sure i would have been mobbed by a thousand people if everyone had it as fluctuating as you did!
