[FFXIV] Main Scenario Quest "Feats of Strength" issue

The Main Scenario Quest titled "Feats of Strength" offered in Coerthas Central Highlands around Dragonhead may cause issues where one of the enemy knights will fall over with the death animation, rather then the "Kneel" animation other knights do. If this occurs, talking to the NPC again after all three have been defeated will cause the NPC to attempt summoning the knights again (and the message stating that battle cries are heard is displayed) but instead, the quest progresses per normal, and goes into the hand-in stage.
