This may not necessarily be a bug but it certainly felt awkward in the game and really broke the immersion. The story mission The Cleansing began while I was in the middle of the mission Air Raid. So I was flying in a plane when I guess I got hit by whatever it was that results in you getting kidnapped by Seed's men. I was just flying around when the screen went very white then turned to the loading screen and suddenly there was a cutscene. Again I do not know if this is a bug or not but it felt really awkward for the mission to begin like that while I was several hundred feet in the air. Just from an immersion point of view I don't see how I would be able to survive this situation since you seem to black out, but from a gameplay point of view it was pretty jarring and I feel like it ruined the impact of this mission but that's just me.
