Character Word Limit

Characters is still limited to 700 words even after the credits switcvh over - is this meant to be? not suree whyy I have beeen advised to purchase a word pack? In fact all the sections in the story bible ar still on words rather than credits. I reead through your info about coming credits and assumed we'd be able to use our credits to top up various sections. But this certainly isn't working my side - is this a bug?
