Then have you already invited him there, spent the day and watched the fireworks? Also Are you doing the Country Road event and have you finished the Bareshade expansion event?
I was asking because you need to finish all of country road's event as well as the bareshade's expansion, to get Logan's second heart and some likes with him, to start the Country road event you need to rescue Vicoria's second prisoner and help him around the farm until he reaches the threshold to take him to visit Bareshade after the visit the event will be on your event log, though you need to have Korg home to progress the event
