I had no such problems up to yesterday playing the PC version from GOG. However, today after receiving the 1.05 update it looks like hacking has regressed severely for me. Whenever I quickhack an enemy (seemingly any targetted quickhack), they become unkillable/undownable/invincible/immortal.

Note that I'm also unable to down them using stealth takedowns. After chocking them, they go down and instantly stand back up without even noticing me.


Anybody else...

After patch 1.05 enemies become unkillable after using any quickhacks on them
