I never exactly understood why does a robot a project your own Sim needs to create at a workbench even gets a tombstone in the 1st place, let alone the most detailed tombstone in game? To be honest the "alien" tombstone/urns looks more like an advanced room air purifier then any type of tombstone I ever seen, they even come with the green on and off button included. I actually use those with BB cheats for simple clutter decoration as purifiers. I think the "living" aliens should have gotten the "servos" tombstone design when they eventually die. The servos tombstone just looks sci-fi to me.
