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)
Every time you rank up, prstige missions reset.
You noticed this too late, since you already ranked up a couple of times if you're defender :P
