I had a glitch recently that resulted in my first handmade servo initializing as an android instead. The servo looked normal (robotic) in the workstation, but when my sim activated it, this is what it came out as:

I have no servo costumes or servo related mods in my game, so this came as a surprise.
The appearance reset to robotic when I traveled with sim and servo, but later there was another glitch: Clive RK300 (the servo) scanned mood and traits of his creator, Connor. The first action worked as planned, but then it looked as if Connor scanned Clive instead. The notifications confirmed my first impression - first I got "Clive noticed that Connor is focused" and then "Connor learned Clive's traits ."

The funny part is that Connor is indeed an android himself (just a normal sim with all the motive freezing traits, no mod involved), so he perfectly well could scan Clive back.
