I built a workshop, added two airlocks on one side and placed a bed inside. As long as I stand in the airlock part, the workshop is displayed and I can see a part of the bed. When I enter the workshop, the walls become invisible and the bed seems to disappear, I just see some small black lines as parts of the workshop. I cannot use the bed. Some hours before I had two airlocks on the other side of the workshop, too, but used the scrapper to remove them. Might this be a source of the bug??
