Lina's quest keeps looping from when you get the cropped sweater to the morning scene after. and multiple other characters quests are locked because I can't progress any further with her(I'm assuming). Can't visit Lera at the park in the evening because the park is closed during the evening. And there is a "Talk to Marina" quest is there but there is no talk prompt only the "Can you help out" action.
So Naya, Kristina, Kira, and Lera all say "No active quest for this character", I sleep and no new quests pop up for them, Could be just another way for you to be saying there's no new content. But I'd say for sure that I'm being blocked for Naya's, Olga's, and Lera's scenes. I can't go to the bakery for the Naya scenes because it says that I need to go with Lina, but that quest hasn't triggered for me. And like I said before no new quests are popping up when I sleep. Another bug I saw is at night when you try to go the living room it shows the background for the MC's bedroom instead of the living room.
