Correct. And no, unfortunately there haven't been any new missions available. Bull made a few posts on it two months ago, including noting he had dropped the ball and caused the delay. There's a few on the way, though we don't know when they will release.
Have fun, by the way, and make sure to check out what the GM rewards are for those two books (I'd consider rotating GMs, because these books, moreso than the pure-SR5 ones, kinda still have the massive-rewards-possible-on-good-negotiation-with-not-so-good-johnson-dicepools, which sucks when as a GM you only get 2 net hits.
Oh, and though we never did get an official statement on how karma would work with FL, I'd assume that max karma is calculated through the SR5 method, which puts Ashes (feel-good) on 8, Stormcrow Undone on 5 and the rest of 6. Then just subtract karma for failed objectives without a mutually exclusive obtained one.
