Well I never considered the forum to be more watched than this… Yes precise click is enabled, I am aware of the tutorial you were following but my setup is not based on that.
By the way in a sense the button there is used just for the visuals and the enabled/disabled functionality of it, you can easily live without it or create your own visuals to simulate mostly the same. You are setting up the Deactivated? variable anyway so you can use that to do some branches on the caught events.
I am in process of figuring out what change caused it but the engine code is not as readable as one would wish and the merges for releases are even less convenient for that.
