The bug in the fourth Chapter. (The Banner Saga)

If people who are in the subject. I decided in honor of the release of part 3 to go over.The fourth Chapter is not suitable Olaf,downloaded another Repack save went,but it's different drove Drago,although other Repack with the guards fought.But no there is not, there is no Olaf.Game prhodila but when you transfer the second part of the write like the company is not consummated and the saves not the rod.What to do then?
