Top-down "Start Following" block does not work as expected

Hi all

I am trying to use the “Start Following” block from the Top Down library, as documented here:

I am trying to get an actor to start following my player’s actor from the start of the game. However, this actor just stands still. I’ve set the blocks up for this actor like so:

But this does not seem to work. I’ve published an example of this based on the standard top-down example here: Tynker

Can anyone help?
