I just posted it so I'm gonna copy paste it;
To get Logan's 2nd heart is a lot more to it; Have him discouraged to go to the Bandit's Camp, finish Bandit Attack, Full Moon, Country Road and 'More Houses' part of Bareshade Expansion.
Once that is done, make sure you have the morale at the Bandit's Camp at 25 or higher, helped Logan out with work and visited the tavern to witness the fight between him and Barrel. Then only what you need to do now is click on your new home at night and it should trigger Logan's visit. (if not, then try again)
