Rank 8 Mastery Test

[Checkmate_001]

I just completed the rank 8 mastery test, but as soon as I finished it, it said mission success, then it flashed the revive option and showed my dead body lying on the floor. I waited for it to work, however, had to restart warframe because it wouldn't leave the mission screen and then it did not update my rank 8 status,
