I was specced into Defender, with the War Machine perk slotted. (Gives you fast reload after you get a melee kill). I had a legendary Primary, Invective Special, and a blue Rocket launcher. This RL had the perk, reloads faster if the clip is empty. It had only 1 shot in the clip, so this activated after every shot. I procced War Machine, killed a few with the rocket launcher, and it reloaded extremely fast due to the weapon perk and the ability perk. Shortly after, I noticed that the fast reload would no longer activate on my legendary Primary, not on Invective. I've tried respecing, exiting, turning the system on and off, and nothing. Other weapons will still get the reload buff from WM, just not my legendary and my exotic that happened to be equipped when I used the super-speed RL. This is on 360.
