Trying to adjust the performance boosts granted to ships when they level up, but can't seem to find the file that governs this information.

Also can't find where those XP values are stored--either how much a ship grants on destruction or much it needs to achieve a given level.

I've got a big file extractor and pulled the contents of both update.big and cataclysm.big, but I can't find those values anywhere. This is driving me nuts. I really want to change some of the variables and create a personal mod wherein gaining experience levels is impossible.

Does anyone know where they are? Or if they're even moddable?
