But the cost of doing so was that most of the available construction room was consumed in doing so.
The next update has some new rooms added, but at the size of my Vault, I literally have nowhere to put them!
Since it's expanded to this size through necessity, I am making a request to allocate some more construction space.
I'd prefer to expand to the right, as I want the mountain to be a rock shield from nuclear bombs and don't want to hollow it out.
That being said, I wanted to put a transmitter room at the top of the mountain, but was prevented from doing so.
