Quest: Burdens Of Command bug?

Same problem. After that the spirit starts wandering around. This is on PC.

Sure you killed the right one? The one that needs to be killed is in the flooded caves.

Can confirm, have killed entire flooded cave, completed all those quests. Came back, spoke for fraction of second to red spirit, chat glitched and spirit is now wandering without being able to interact with it. I even tried a party with Cole and Solas, as it is a spirit. Nope. 

Same here, the Demon is dead, spoke with the Ghost for a split sec then he moved off and I can't get my reward

Thanks for the reports. For my part, when I arrived the spirit had a glitched conversation with me, but then wandered off and I never got the quest in the first place. 

Can I confirm which platform everyone is on?

Spirit glitched when reporting death of Rage Demon to i. On PC

you can leave crestwood and come back and talk to the spirit

i.m on ps3 ind it happend to me as well

Same issue with turn in. PS4.
