This mod disable the ECM Jammer "Feedback" function while the game is in stealth mode. (stunning cops within a short distance from the ECM)
It prevents "missclicks" from you or players in a stealth mission that could go loud if pressed (which is quite embarrassing).
Installation:
Simply unrar the package with WinRar and drag the folder "No ECM Jammer Stealth" into your Payday 2/mods/ folder.
