I'm not sure if there are undos involved, but the only time in the game where Continue was followed by playing and gaining a Wayfarer, no Silver was gained.
But I know that the implementation of "Return to your Action phase" has an incorrect timing on dominion.games, so it seems plausible that the Silver gain is handled incorrectly with regard to Footpad.
