The bug: button is held when only tapped.
This is an issue I have noticed when attempting to only crouch but ending up prone because the button tap is getting hung up from a lag spike. While driving the M3S with another player in the passenger seat, they were ejected from the vehicle as a result of this bug. They attempted to close the door and their square button was held, it would have been funny except we were being chased by other players in a vehicle. The M3S was lost because I attempted to circumnavigate around and try to save him, but nonetheless the situation would have been very different if the controller’s button mapping were not set to have square interact with opening/closing AND holding same butting to get in/out.
