dragonslayer quest bug..

[Ẑara]

after I talked with 3 heroes,they run outside and I followed them,but none of the heroes says that we need to shout together, and if I try to do the clear skies shout, nothing happens..
I don't have previous saves.. cuz I only do quicksaves.. I mean I have old save ,but before couple of days,but I don't want to start over from that one..
please help and thanks in advance

No autosave?
You could try and set the quest stage via the console, but I'm not sure it will help with the mist itself. You can try quicksave before the shouting part and reload, it could fix it. But the best course of action is to reload a save before the quest begun.
Or download the Unofficial Patches, it could fix the problem mid quest

You should always do hard saves before you change cell.
Quick save is not that good, it is what the name says. Quick. Sometimes it dont save all things.
And install The Unofficial Patch it should fix that bug.
