Inconsistency with hints and scene flow (semi spoilers)
In Hints when I clicked on Serena, there was no "Talk to Katie." I pick Serena scene, get a reference with a scene with Katie (can't remember if its from V0.7), pick Katie and see the scene that's referenced in Serena scene.
Spoilers further down-
Its the talking about encountering Lunar part, when I haven't encountered her yet.
