Effects not applying from specials
This has happened with Magik and Guillotine for me so far. SP2 in both cases. You do the special, it lands, and the effect doesn't apply. It's not consistent, and so far I've only seen it happen in AQ. For Guillotine, it happened against IronMan on map 5. Landed the L2, but the phantasm never applies. Actually happened twice in the same fight with her. With Magik, it happened on several different nodes within map 3 and map 5. I'd estimate about 1/10 attempts to use L2 did not apply power lock.
