Basement no longer accessible

The cellar is no longer accessible, but it's still there. Power from below is still working. I went in using NoClip and everything is still there, but the hatch won't let me in. I have no idea why. All the files are still in the data folder and everything is there. The console has loaded everything, including structures, but the hatch won't let me in. How do I fix this since all my loot is down there? How do I get access again? I tried creating a second entrance, but then I had the same problem. Then I went outside my base, built new foundations and an entrance (a new cellar), and that worked. I don't understand it.
