Cornetts Call quest can't progress because of a bug

[3x0du5]

So I was doing this quest , found both peaces unlocked the temple sneaked trough the boss and looted the room , however the quest won't progress further i can't report I found the temple

I completed that quest several times with no trouble. The difference is that I didn't sneak past the boss, I killed it.

I am very sure you can finish the quest without killing the boss. You just have to sneak very close to the top left corner to get the quest log updated. You do NOT have to kill the boss. I have done it several times this way.
