The game should keep any type of Debris as Kerbal does

@SamTheFox thank you so much Sam, I'll try that and experiment with it and inform you if it worked as you mentioned.

imagine that a part with the setting enabled is an energy core preventing everything that is intact to it from disappearing

so i guess you could if you really wanted to make sure that there was absolutely no disappearing whatsoever, but for certain subassemblies that happen to escape your rocket just require 1 part with prevent debris on

@SamTheFox but in this case I'll have to enable prevent debris for each individual part? Or just the command pod and it applies to the rest of the ship?

turn on tinker panel > enable prevent debris
