Astronaut sounds in main menu

Picture of planets only because it's hard to photograph sound.

I booted up the game to load into a lone astronaut standing on Earth, so i undid my flight, which brought me back to the start menu when you boot up the game. I then went to Resume Flights, and deleted 2 ships, one of which had 15 crew aboard. Right after, when i pressed the back button to go back to the menu, an astronaut oof sound played, and was played every time i backed out of the Resume Flights menu. I will attempt to reproduce it.

Edit: I have successfully reproduced it.
1. create a capsule with max available seats, and fill them all.
2. Spawn into low orbit/get into low orbit
3. Place one astronaut on EVA, and deorbit with your jetpack
4. After you land/splashdown, close the game. Do not save and exit, just close the game.
5. reopen the game, and it should load you directly into the astronaut on ground. Undo and Exit to go back to the title screen.
6. go to Resume Flights and delete the craft you left in space, then press the back arrow. When you do, an oof should play.
