You could be right. The Perry Poole one was a weird case of a special episode as well in which 2 episodes were broadcast on the same night although split by another programme being broadcast (something Cilla Black related i think, if my memory serves me correctly?).
Or maybe Challenge just didn't get or show it because it was a special Christmas episode and was for some reason handled differently to the other episodes, that has happened with other shows of their down the years, where they've skipped over Christmas and other special editions, even though they do exist.
