Here is what i discovered. Phase one, do a test char. I've named it Test'O'Char. I've then bought baking, and i've done the tests.
First i baked some delicious honey buns. I've used 0.3 liter -2^31 honey and 0.4 liter of -500~ milions i've got yesterday (the quality is averaged when you take the honey, that seems to be always -2^31 q; since i had some normal low quality honey, the result is near to (-2^31/4)q honey; by the way, putting together two negative quality honey gives positive q1 honey) .
This is the result of baking those honey buns.

Then i decided to eat one of them. They didn't give me feps. Obviously, since their quality is below 0. I've been expecting that. So i've eaten other foods (the bread you're given at the start of the game). And i've got this.

FEP overloading. Or i should say a negative number of feps. They aren't displayed, of course, but they bring the FEP counter in a huuuge negative state. The game don't visualize negative numbers of feps, but they are still there and they are the reason why i can't take that cos point. I hope this can help in resolving these problems.
