Hello there.  I'm hoping that someone might be able to help me out.  I found the option to allow "Flaws and Traits", but when I click on the "Add Flaws" I'm receiving a "Nothing to chose from!" error message.  I purchased the pdf from paizo that lists Players Options Flaws, and by taking two flaws, I get to add two more Feats...  Can anyone explain to me how to use the Flaws feature please?
