On many occasions whilst playing Crota's End at the Crota encounter the sword once dropped by the swordbearer just vanishes literally seconds after his death - there's no time to pick it up it just disappears and throws us straight to the ogres. Usually when we had a really good first run with the previous sword. Why would you allow a glitch to remain in the game where the main object that allows you to attack the main boss simply just poofs into thin air. Yet you wonder why people cheese the hell out of this game because the glitches make it impossible! How can you proceed with no sword. This is a must fix.
