Unable to finish memories event in Rune Factory 4 [duplicate]
Solution 1:
You probably missed talking to Raven after the scene with her and Dolce. You should get a surprisingly long conversation with her about the nature of family. (I didn't immediately realize that the conversation was part of the event, until I started wondering why Raven was so uncharacteristically talkative.) If it's not Raven then it'll be someone else you need to talk to, so talk to everyone.
