I wonder if it would be possible to slice off the “forty” in “forty-two” when 3PO says that the celebration only occurs every 42 years. That way it would only be every 2 years, which is slightly more believable.
Yeah, I know it’s meant to be the difference between 2019 and 1977 (release year of Star Wars), but honestly that’s a really strange easter egg considering the fact that it no longer has any meaning in 2020+.
