Level 52 concealment operative passive: "increases your effective stealth level by 2. In addition, when you activate Exfiltrate, you dodge or resist all incoming attacks for 1.5 seconds".

 

I have noticed recently snipers/mercs/assassins having some abilities that seem to do damage through this passive.

 

at first I just thought it was lag but when my connection was good and I was actually looking for the buff to be present on my character I still noticed some attacks would occasionally doing damage despite the buff being present

 

snipers: ambush

mercs: heatseaker missles and net

assassins: discharge and maul

 

playing concealment is fun when you look to use your roll to avoid incoming damage from a large attack but on multiple occasions I am looking to avoid these attacks, have seen the buff present on my character, yet still take damage

 

has anyone else noticed anything like this recently?

No, it's working as intended for me. May be you are actually lagging or just roll too late, dunno.

Commando net goes through roll 100% of the time, Mercenary net however doesn't go through it at all.

Multiple knockbacks goes through it randomly too.

However none of the others you mentioned (Maul, Discharge and Ambush) does not go through it. Atleast i haven't noticed
