I experience periodic nano blitz 'detection' that stops my pass rusher before he can make a sack in CFM without having implemented any nano cheats.
Here is video evidence of my edge rusher (Ogbah) beating the right tackle and being stopped in front of the QB.
This happened twice in the same game. Not sure if EA checks this thread or if there is a better way to draw attention to this seriously annoying / game changing bug.
