I've noticed for a couple of weeks when I run across a patcher NPC it's harmful code doesn't land on me.  I think sometimes the NPC will free fire before the cast timer finishes.  Other times it doesn't deflect or do any damage.  I haven't seen in my system chat it me resisting it.

NPCs also break root when they wish, move and still be able to use buffs and hacks, cast a hack die and the hack still affect you, no reuse times on IL....

Basically, they are mad 'sploiters
