cyion: I was mining a lot of heridium on the surface of the planet and the sentinel flew by me multiple times and didn't care. Is this a bug or have I reached such a high opinion with the Korvax that the sentinels don't care anymore if I mine?
Sentinels come with different stages of "alertness" (shown while landing on any planet/moon). Additionally they will react different to mining and actually killing beings/things.
Been at a place where the info at landing showed the sentinel as being "frenzied", printed in red.
So yes, they differ a lot in the way they will react on your behavior.
Once your tool has the upgrade for this shrapnell kind of "ammo", sentinels will become more or less harmless and easy to nuke.
