Life is Strange: Double Exposure

In Chapter 4 near the start you will arrive at the bar for the Krampus party. Talk with Reggie next to the projector, shift to Dead world to find Moses and talk to him. Follow the instructions to break the projector. Now get Living Moses to fix it and you'll go back to talk with Dead Moses. He breaks part of the gingerbread house so go to Living world and find a replacement. Go to Safi and choose the gingerbread option than give the chimney to Dead Moses for the achievement.
