Ah sorry, looks like I was wrong, cloning entities one by one doesn't work:
/c
people = game.player.surface.find_entities_filtered{position=game.player.position, radius = 15}
for i,j in pairs(people) do
if j.name == 'rocket-silo' or j.name == 'rocket-silo-rocket' or j.name == 'rocket-silo-rocket ...

Cloning a rocket doesn't clone it properly. The cloned rocket's inventory (for ex.: satellite) disappears, and no rocket is launched when clicking "launch" button.

I can see the issue has been mentioned a while ago here and it seems all the issues described here remain: https://forums.factorio.com ...
