I found a glitch in the daily mission system in which I can do the mission twice in one day
How this is achieved is that I finished the mission first and as I rank up to a Defender doing other missions,
I found my daily mission icons mission a check mark, so I was curious enough to do the mission again and found this unusual bug in game

I am not sure if this is actually a bug, but if it is please don't take away the extra 60 prestige I've earn (thanks)
