i have got the same problem for the storage expansion, even on a lower level. i had 520c, full kernel stock, then bought an expansion for 500c, but somehow im at -480c
I loved playing this game, i almost beaten the game, im only missing the last champion. i only used for the whole run blue and green cards, i might try a run where i only use the red ones for a change. if you have any original game you've done i'll check it out
