I'm trying to complete the Brun the Bard quest. Brun wants you to kill enemies along a path to clear the way and he tells a story after each objective. I'm stuck on the second objective where you need to clear out the enemies in front of the castle gate. I killed everyone and mission won't progress. Brun wont run over to me and if I go to him he tells me to clear the gate. Is there a way to bypass this bug are is this a mission I will no longer be able to complete?
