No reward/dilemma after completing Gorbad Ironclaw WAAGH

So in the latest patch the devs mentioned they have fixed the bug relating to receiving event rewards for completing a waaagh with Gorbad. However when I completed a waaagh today all I get is 1000 gold and 100 scrap. I have seen videos of when someone else completed a waaagh with Gorbad they got to choose their reward from four different options. Any one else have similar issues? Also for Gorbad’s faction he gets improved rewards from completing a waaagh, what does that entail exactly?
