Guns rotating incorrectly in first-person view

We kindly ask that you complete the questions below. With this information, we can add it to our database for investigation.

Issue Description:

Gun models in first-person view can become pitched (rotated ‘forward’, away from the player) during play. I’ve noticed this particularly with the Lucius Helbore and the Vraks Headhunter. When this happens, iron sights on guns can become occluded by the gun’s model, making it very difficult to aim. Once this happens it seems to become ‘stuck’, and remains that way for the rest of the mission.

Steps to Reproduce:
Play a mission with one of these guns.


Reproduction Rate:
Very often.
