It's nothing gamebreaking or even influencing gameplay, it's purely visual but at the same time it's somewhat confusing and silly.
99% of the time last kill on non-respawn mode like Elimination or Demolition is made with Sitara's drone, the victim will not die for the most part.
Victim's HP will stop at low number like 3 or 5 and round will be declared lost for his team due to every member of the team being dead which is confusing him and surrounding/spectating players because he's still standing, holding a weapon and having some health. This is not just a "local" bug, once it occurs it's same for everyone - all players will see given player as alive whilst match ends due to enemy team being wiped out.
Just wanted to report that one.
