BLC Awareness is also stuck at 50%, is this the way it should be? Can´t buy more advertising at the study either and the weekly meetings do not change anything.Progress the other characters, your probably locked out because you haven't finished the stories enough to have them at that point.
Hmm it seems as Tiffany is also gone, no text messages no nothing, I´m also missing 1 entry in the "Journal Menu" could it be her?
