Your logbook holds all the side-mission stuff you've yet to complete, and when a section disappears, that means you're all done. Except my DNA report states I've only completed 66% of my Assassination Contracts, however that section has disappeared from my logbook. I've spent a couple of hours running around New York and Boston and can not cause any new contracts to pop up.
So is this common? Anyone know of a work around to force these contracts to pop? I'd hate to restart from the beginning seeing as how I'm 84% complete, it'll take another 40 hours or so to get back to where I was.
