I can’t seem to replicate this bug on my end. Could you share a bit more info? Like anything out of the ordinary you might’ve done before the issue happened.

well when you talk to your friend (in mine case was) and explorer the her house, it found the picture and than try to leave the town it say to me that i neer to talk your friend. so that was the bug that happens to me. so when i walk back in the house and i see the friend inside the house but can't talk to her or something else. so i did restart the game and skipped that house exploring and than it accept than well. it was little bit weird bug to me.
