Standard droids have several annoying, humanlike traits.

[MrUregancho]

Colonists will attempt to romance droids which will always be declined and therefore always result in a negative moodlet

Droids will have "look change desired" event even though they cannot desire anything

Droids will claim unoccupied beds even though they cannot sleep.

Droids will attempt to use the neural superchagers despite getting no benefit from it

Droids will attempt to use drugs like smokeleaf despite receiving no benefit from it (This one can be avoided with drug policies but still weird)

All above issues occur with DROIDS. I have not used the higher tiered ANDROIDS at all.
