The light is off and i can retract it and deploy it i opened it and closed it over and over trying to escape, could it be because i was in combat and we cant FSD while in combat??
You can FSD in combat, but a heavy ship might mass lock you. Just like a station or a celestial body can mass lock you.
This is clearly communicated though.
You specifically said you got the message "
cargo scoop deployed".
If it wasn't and you are sure about that, then it sounds like a bug.
I have never encountered this bug though in almost 2000 hours of playing the game and I never saw it mentioned on the forums.
Perhaps you could try to reproduce when out of combat.
You might then check with the external cam whether the scoop is actually deployed.
got some materials off him whatever that means
The materials you picked up can be used to upgrade your ship at the engineers.
You do need the Horizons expansion to access these engineers as the known ones live down on planets..
