I find it really strange that people are advocating for a system where you can know an organization's darkest, most carefully hidden secrets (FL+20) but not know the basics of how it operates on a day to day basis (CL).
In those few cases where this applies after a revision; prerequisites. Also, this might not be as strange in many cases as you'd think. I may know military secrets (...and I actually do, to an extent) without knowing exactly how the military hierarchy is determined (...which I actually don't).
Also, I want to again mention how inappropriate of a name "Common Lore" is. It really should be "Mundane" lore, since "Common" implies that it is commonplace. The difference between Common Lore and Forbidden Lore is whether you can be shot for knowing what you know or not, not whether it's common knowledge or esoteric (even if it often works out that way).
