While attempting to chain the heavy attack of the super from the super's light attack. I noticed that I was unable to use the super's light attack after successfully performing the combo. It didn't allow me to use the light attack as it looked to be on cooldown (greyed out) while in super. I was not able to replicate the glitch in private matches by myself. I was able to get it to happen again while in a strike and while I wasn't recording the instant it happened, I did capture a bit of the aftermath. It seems like the melee doesn't go into cooldown during super but rather is completely locked down even after super and the melee ability is not available after the bug occurs until I die.
