The game uses both spellings of "filet/fillet". I believe the word "filet" in french is always a noun ("le filet", but correct me if this is wrong), yet this is one of the spellings used for the verb in-game.
Whichever spelling would probably be acceptable if used consistently -- but if there were to be any difference between noun and verb, it should maybe be "filet" for noun and "fillet" for verb?
