Unlike in the gunman styles, the MA grab animations work perfectly (apart from finishers) if used in Interlock against a Gunman or a Martial Artist.
I'm not so sure about the other three Exile types, but if your opponent is a Lupine, any grab attack in a hit-hit round is bugged each time. It doesn't matter if the attack is performed by the Lupine or you, the Lupine freezes while you're performing the according animation each time -- actually, I haven't seen it work correctly at all.
It's the same with Kung Fu, Karate, Aikido and Self Defense (although I'll check out the last one again) by the way, and it doesn't matter what kind of Lupine we're talking about: It happens aswell with male Lieutenants using Self Defense as with the other three types using their unique Lupine style.
Also, I'd like to point to an other animation bug that sometimes appears during special Lupine abilities: It's the same as with the grab tactic, the Lupine doesn't budge while your character acts like being hit by an invisible enemy; the one I have in my mind is where the Lupine puts you down and then performs several attacks on your throat. Sometimes, the Lupine just keeps standing while you fall down and start twitching like in a death struggle. That doesn't happen often, and as far as I recall, it only concerns this animation, althoug I'm not that sure there. If I should spot anything more, an update will follow.
