archwing quest is broken

[(XBOX)CyclonicTundra5]

So I recently started the quest in which you get the Odonata archwing, and I had problems straight away.

The first mission worked fine. It was the mission in which you're meant to get the Odonata wings blueprint. No matter what I did, nothing ever worked. The game would just stop on the loading screen barely past halfway, and I would need to quit and relig each time. 

I uninstalled and reinstalled the game yesterday, and it worked fine. However, the next mission has the exact same problem. 

Im not reinstalling the game every single mission, so I hope this is fix very, very soon.

Thanks.
