Has Candyland always had a lose-a-turn square?
No.  The version I played didn't have those; it had three spaces with "sticky" dots (largish, round, and black).


  Before the 2004 version, there were three colored spaces marked with a dot. A player who lands on such a space is stuck (all cards are ignored) until a card is drawn of the same color as the square. In the 2004 version, dot spaces were replaced with licorice spaces that prompt the player landing on it to simply lose his or her next turn. If you land on a piece of gum, you go back to the start.
