Does anyone know where the career icons for the UI live in the game files?

I used lah7's 4k ui patch to scale up my ui, but something went wrong. The icons for the careers in the career panel are way too big for some reason, and reverting the patch doesn't help. I'm pretty sure I could fix them by scaling them down manually, but I can't for the life of me figure out where they're stored. I really, really don't want to have to reinstall the game.

I've got the Double Delux CD version of the game.

These icons are in objects.package of the latest expansion pack. Each career is a pseudo-object with the name that starts with "JobData -". Each of those objects has resources called "jpg/png/tga Image".

Thank you so much, I'd never have found those on my own.
