Destiny 2 update 4.1.0 shipped with a bug where a solar hunter's melee charge would not get refunded while both radiant and using the Knock 'em Down aspect if the only enemies killed by the melee were exploder enemies, shanks, or harpies. If the final blow with the melee was supposed to proc an ignition (easy to replicate with Caliban's Hand, which is supposed to proc an ignition on every direct hit final blow), the ignition wind-up sound effect will play if the affected enemy is a harpy or shank, but the ignition itself will not proc with neither of those, nor any exploder enemies. Both of these issues can be replicated in-game with 100% success rate, and have been reported multiple times, yet have never been acknowledged as existing issues in a TWAB article.
