I have the latest version of Kerbal space program.. I decided to add interstellar and as soon as I did I had to uninstall it because it made the game unusable when it building mode as soon as you click on an engine it would be firing and nothing would work so I did a little testing and went into war plug and I removed two ( tweak and the bitton one] and it worked again.. if I install both from site it still works but no reactor engine sounds...
