With so many things and features still not in-game i dont think that will have any priority anytime soon, still they where invulnerable in the previous version, so at least they can die now, in fact the game improved a lot from 0.60 to 0.61, the companion AI is really bugged, they get stuck, like other npcs, they do not use healing items, or even consume ammo, also it has been say that one could put a companion to work, like chopping down trees or mining, that just dont work now.
still i starting to like enemy AI, they are not very inteligent yet, but for animals works quite ok, espacially the ones that attack in packs, so far the world is really dangerous just with animal life, especially in the forest, so many predators that attack in packs.
And the Elysium is performing quite good as well.
