Fireteam Glitch

(this is not something that will help u win )
I played an "extreme" level fireteam and we lost (no suprise) Then I left and quickly joined another "extreme" level fireteam and the "Mission Failed" window w/ all the stats was on the screen while I was playing the entire time...

Does anyone know how to prevent/get rid of this if it happens again

Thanks

u cant nexon failed again...
