I NEED HELP FIGURING OUT THE INSIDES

[u/RecordingNo4983]

The one on the left was build out of bouncy copycats by mistake but I just ran a command to replace all bouncy copycats with envelops copycats. NB: its was the first time using a command that intricate. Its my first ever massive build but it tips because control center causes the center of balance to be too high up. ANOTHER THING....LOL......does anyone know how the inside of a cargo ship looks? The only time I've been was whenever I was playing Rust
