What plot holes were eventually addressed in sequels or expanded material?

I recently found out thanks to another thread on this Subreddit that the Disney+ The Santa Clauses TV series actually addresses several of the plot holes from the original Santa Clause movies.>! It turns out that the previous Santa Claus actually chose Tim Allen as his successor, the previous Santa actually didn't die and the elves all knew it which is why they seemed so indifferent about it, all of the "clauses" in the contract were made up to help Tim Allen become a better Santa Claus, and there was no previous Mrs. Claus thus explaining her absence. !<

What other plot holes that bothered you were eventually addressed later?
