Make the traitor signal jammer block PDA messages and implant crit/death alerts

[coolvape]

and with cutting cameras actually functioning properly now, it happens or is noticeable a lot more often. i play AI a lot and if i saw an area suddenly blocked off from my vision, my first assumption would be "cameras are down" not "oh, there's a signal jammer". hell, people sometimes cut cameras even when they're not doing anything suspicious.
