About 1:30 in to the show Willona's New Job, Willona is so excited about becoming the head buy at her boutique.

Yet, the ending episode of Good Times, The End of the Rainbow, she suddenly is happen that she "just now" became the head buyer.

I watched all episodes after Willona's New Job and no single episode said she lost her promotion, including said episode.

Also, I would think at the end episode she would have said she got her promotion again or something.
