I've tried updating the grid with the new rooms, but for some reason it won't update. Even though it says it now has 770,000 PCU instead of 560,000, when I load it into the world, the old version appears instead of the new one. If anyone has any ideas, let me know. Otherwise, I'll just create a new workshop again.

I've just added new photos to the post.

I have added a new description, I have also started to create the Atrium, the Spartan Bay and several corridors. I have also fixed temporary things like the engines and I have added engines inside to stabilize the ship.
