There is currently a bug during the final epilogue cutscene of the main campaign where some camera angles are obscured by an out of place/duplicated character model resulting in some of the camera shots being  obscured by close up shots of armour rather than the character who is speaking. It is not a game breaking bug but it does ruin the tone of the scene. Hopefully this will be fixed soon and the rogue space marine reprimanded and returned to their post.
