Firefight scoring/ranking

Has anyone else found themselves the highest scoring player during a firefight match but not in actual first place? What’s the cause of this?

I’ve seen it couple of times myself, having the highest score being placed in the 2nd or even 3rd place.
Weird.

most times that ive seen it usually it seems that me or someone in my fireteam didnt get the point for the final boss but if they had would have moved to those places. not sure if it just wasnt showing up correctly or if its just some weird bug

Yeah it has happened to me a few times. I think the bug occurs when ever someone in the top 3 gets the final kill on the mythic boss.
