I am unable to complete "Striking the Heart" quest. I don't suffer from the same bug where the enemy is already killed. I was able to kill the Silver Hand leader. My quest log tells me to talk to Aela. When I speak to her, I get no options to complete the quest. What are my options? I received this quest a while ago, went off and did other quests, and then came back so loading up an old save isn't much of an option for me. I am playing on Xbox 360.
That quest was bugged for many players since PS3, unfortunately PC users have access to commands to mark the quest as completed. For PS and Xbox this could be a problem.
Maybe this thread can help you:
"Some players have reported that after finishing the two radiant quests for Aela, Blood's Honor won't show up, as Aela won't initiate the quest. This may be caused by a conflict with a radiant quest involving Glenmoril Cavern (Search for the "Iron Mace of Torpor" being an example of this). Attempt to complete the radiant quest as early as possible and it should function as normal."
