The voice interface for voicehook was removed with an update a long time ago, so it still requires !w. Unlike CSGO, there isn't a OnVoiceTransmit function to hook onto. I'll look into a workaround after this weekend
Speaking of this weekend, I won't be home to work on bombs (@Hidingmaster). In my opinion, they should be fine now that bank doesn't have interest. If need be, @DrLee can always set the bomb cvars to one specified in an old conversation (Bomb cvars are in server.cfg).
