GamepadIndex is always -1

Two PS4 controllers have connected successfully via bluetooth, but there's a strange error showing up in the gamepad object.

In the event conditions, these gamepads have two separate gamepad indexes. But gamepad.gamepadindex is returning -1 for both.

Is this an error with my code or gamepads? Thank you for any insight!

According to the manual, this expression only works in "On gamepad connected/disconnected" trigger, or when using "On any button pressed/released" with a gamepad of -1.

Thanks for looking into this!

You're right - it succeeds if you work backwards from a button being pressed, instead of forwards from a gamepad index:

But the first approach seems like a bug; construct knows the gamepad's index in the condition, but not in the action?
