Jumpmaster bug mid-fight

If the jumpmaster died during a fight, sometimes it cause other teammate to become the next jumpmaster. For example, 3 players, Ash, Mirage and Bangalore, Mirage is the jumpmaster on the start, 10 mins later they fight 2 squad, Mirage died, causes Ash to become jumpmaster all of a sudden, but Ash was knock before that happen, Ash died at the same time as she became jumpmaster, causes her to be able to see enemy near their remaining teammate, Bangalore, around 20m range. No tracker used, no survey beacon used, just all of a sudden have an enemy radar with around 20m range.
