I've had the same issue with the larger bunker in the wasteland spawning 5 block lower into the ground and the last floor spawning in the sky. My friend was able to get the portal power source still by interacting with the portal that spawned in the sky. However; when we try to use it on Anna's door it doesn't open so we can't access the laser workbench. Any fixes or workarounds anyone can suggest? We are playing on a server and not peer-to-peer.
