The SiFA on the 442 experiences some strange behaviour. Please note that I'm using an Xbox controller with my PC. When pressing the B button, it will only cancel SiFA if the warning icon is on the HUD. Unlike all other trains where sporadically pressing B stops the SiFA warning. To me this doesn't seem correct, as it's the only train that exhibits this behaviour.
That’s a new feature for controllers. The controller button for Sifa / PZB only acknowledges what neeeds acknowledging at the moment.
I'm assuming this has been set up per stock as opposed to in general? Because the 101 still behaves as per normal.
