Input Action Not Calling Function

I have an input action in my TSpaceShip class that looks like this:

PlayerInputComponent->BindAction("MainThrusters", IE_Pressed, this, &ATSpaceShip::MainThrusters);

But it doesn’t actually call the MainThrusters function.

For the purpose of debugging, MainThrusters() looks like this:

void ATSpaceShip::MainThrusters()
	UE_LOG(LogTemp, Log, TEXT("MainThrusters : On"));

I’ve tried using input from blueprints to diagnose the problem, but the input still doesn’t work.

And the action mapping itself looks correct.

Additionally, the pawn is auto possessed using AutoPossessPlayer = EAutoReceiveInput::Player0; in the constructor, so that isn’t the issue either.

I’m really at my wits end with this issue. All input works perfectly except for this one.

I fixed it by just changing the name of the input action from MainThrusters to Mains. Still don’t understand what the root of the problem was.
