that is an error I haven't seen in a very long time.
it's because the specific function called by bobelectronics cycles through ALL recipe prototypes to look for a specific ingredient. If another mod has set up an ingredient incorrectly on a recipe, the function flips out and crashes the game.
I've looked into crashproofing the function, but it's not easy, and considering it's such a rare occurance caused by another mod fucking up, it's been low on my priority list.
