Animation Playback Issues

[Nertea]

I have an issue with an animation not playing in reverse properly. It uses the landing leg module and is... well, a landing leg. This is the bit of the cfg file here:

MODULE
	{

		name = ModuleLandingLeg

		animationName = LegExtend
		wheelColliderName = wheelCollider
		suspensionTransformName = PistonB_extender
		orientFootToGround = true
		landingFootName = Foot
		// Axis is aligned forward instead of up
		alignFootUp = true
		suspensionUpperLimit = 0.47
		impactTolerance = 450
		suspensionSpring = 5
		suspensionDamper = 2
	}

The animation plays correctly when extending the leg, but hitting retract just sets the animation to the first frame instead of playing the animation properly. Anyone seen this before and have any ideas on what to do?

I've already tried every single animation wrap mode in Unity, just in case, with no joy at all.
