The rats don't eat bread

[Zeddicus87[DE]]

I would say the title says a lot, but the fact is that I switched to bread production. Before that, my rat residents only ate the grain. That worked, now I'm baking bread and suddenly I know that all my rats are starving, the first ones have even died because they don't touch the bread. Do you have to give them permission first or is this a bug? Does anyone know more about it?

Bread is for middle and upper class only by default. You have to pass a law at the code stone which allows the lower class to eat bread.
