In the video you can see that when pressing LT on my gamepad, sometimes input doesn’t register, players in my game are also facing the same issue, for now it was PC players with controller connected to it. It could probably happen with RT/R2 too, I’m assuming it has to do with how you press the button since it can be lightly pressed or go all the way, IsGamepadButtonDown also fails to recognize if the button is down or not when this bug happens, and can be replicated perfectly, just press the button in different patterns to see if it happens.
