So I left my base to get some resources. When I came back the main room was gone. Like completly not there. I had to build a door just to get back inside, and now I have no way to teleport from base. I built an additional round room hoping it would turn into the "main room" but it did not work. Do I have to find a new habital structure and start over?

EDIT:

I restarted the game and the issue resolved itself
