Fichina, the ice planet that was introduced in Star Fox 64, is infamously erroneously called Fortuna in the English version of the game. Fortuna was previously the name of the jungle planet from Star Fox on SNES filled with monstrous and primordial creatures. It was also infamously dubbed "the Dinosaur Planet", years before the Star Fox series would incorporate another Dinosaur Planet with Star Fox Adventures.

However, looking through leaked SF64 files from the Gigaleak, there does seem to be evidence that Nintendo dubbed Fichina as Fortuna for most of SF64's development, only to change the name to Fichina at the tail end of it. Almost all of the source code refers to it as Fortuna, and the internal file system has “FO” appended to all of the stage’s assets. The image file Nintendo provided for the stage name to be translated is also labeled FO_E_FO. With the decision to rename it to Fichina seemingly being a last minute one, it's possible Nintendo of America were not brought up to speed by Nintendo's Japanese branch of this lore change when they were originally localizing SF64.

Nonetheless, Nintendo has since firmly established Fichina and Fortuna (as it was in the SNES game) as being their own distinct planets, with both appearing together in Star Fox: Assault and Star Fox Zero. Strangely, in the former game, Fortuna's Japanese name フォーチュナ (Fōchuna) was slightly modified to フォーチュナー (Fōchunā), which would translate into "Fortuner" in English.
