Pretty much as it says on the title. After grinding crucible pretty much constantly, I was overjoyed when I finally got two precision kills with Whisper from across a map (more than 50m, as checked with DARCI), and though I died immediately after, I didn't reload, never had mulligan proc, and never swapped weapons, yet the Mission Control medal didn't pop.
Other pertinent information: a friend got mission control in a similar way; in momentum control, using revoker. i did the exact same thing, just using whisper instead. and yes these medals can proc in momentum control.
I just want to finish deadeye man, help?
