Is getting a perfect parry and not getting a gun strike supposed to be a thing? 

Because I made about six or more perfect parries in a row against some tyranids and got nothing. 

I do realize you don't get a perfect parry/ gun strike against the first/ second swing of a combo. Not talking about that. 

Is this just ANOTHER bug that's crept its way in? 

This was with Sniper.

I've also noticed recently that the parry and auto scan on Tactical isn't working all the time either, now that I think about it.
