While there is a known engine limitation with weapons only being able target units on the specified layer, that Megalith looks like it should have still been on the land layer (unless someone adjusted the transition offset without me realizing; this problem has been brought up before). I have no idea why there'd be a difference between auto-fire and manual orders though.
