If you look at your leads, you'll see that some of them say "no more content in this version" at the bottom. A continuation of that particular storyline will actually be in the next update (Sunday for Patrons/Subs, Wednesday for everyone else) :)

Roxy doesn't have any leads - she only has hints in the heart menu card. As for the other leads, I've checked my code and I can't find any misplaced "no more content in this version" text, so if you can tell me which leads specifically were showing that (which then let you continue) I'd appreciate it.
