I just noticed this while preparing to Trick-or-Treat. Outfit #77 is listed as "1000th Birthday Suit" in outfits.txt. I think this was the original name when it was first implemented, but it has been changed in-game to "Thousandth Birthday Suit". This effects the outfit name in modifiers.txt as well, of course. The information on the wiki matches what appears in-game. Not a big deal but figured it was worth mentioning. Thanks!
