Sorry if this is the wrong place to ask.
I am a lvl 52 Trooper. I am performing the Rakghoul event down in the tunnels. Every now and then, I would get an infected corsec officer that just would not take damage. They told me they are only invincible the first round. But I stood there for several minutes being kept alive by heals attacking him, and he was taking NO DAMAGE. No gold or silver star on him, just invincible. Then somebody else comes along after mentioning, kills him instantly. My equipment and everything was in fine shape, just that 1 out of 5 of these guys were invincible.
I have searched, but have not found information on this. What am I doing wrong or was I bugged? The lag down there was high as well.
Thank you.
