In the final area of the Automatron dlc every single robot turns hostile emmediately. But I have no problem killing them. But there are two enemies I can't even kill with a direct hit from a fatman. Those two npc's are known as Spark (eyebot) and The mechanist (main boss). Their hit boxes aren't responding to ranged weapons so I figured, hey might be the invisible robot hit only with melee weapon bug. But no alas even melee does not work. This is pretty frustating because, it basically ruins the experience. Also I cannot select them through console and cheat my way out of it. so my question is: Does someone have a fix or a workaround for it?
