[1.7.2] shadow simulacurums casted by NPCs don't do anything

[Zeyphor]

when an enemy anorithil casts shadow simulacurum on you, it doesn't attack you
in fact, it doesn't do anything at all
it is presumably missing its AI
this happens every time an enemy anorithil casts shadow simulacurum on you, without fail

[Zeyphor]

after some contemplation, and some experience, I've realized that, every single time a hostile NPC casts shadow simulacurum on me, the camera immediately centers around the shadow simulacurum
this suggests that the shadow simulacurum's AI is looking for the player's input, but it won't receive the player's input because the player is controlling the player, rather than his simulacurum
perhaps, if an NPC uses shadow simulacurum on a player, and then uses rune of the rift or time skip on the player, then the game will let you control the shadow simulacurum during that time skip or rune of the rift

Simulacrum is definitely buggy, also was getting a ton of lua errors every turn one time but even normally they don't move at all.
