I would recommend to keep using the old version until the mods do something. If you want to download the old version check this https://www.speedrun.com/fnafb/thread/hm9pd

BB stats were changed / fixed in Q Scenario so yeah they sould make a new category The current categories are for the version 2.1.0 (older version) while the new version available in gamejolt is the version 1.6.1 yes that is correct version number.

if you want the "2.1" version here is the link https://web.archive.org/web/20220111140320/https://cdn-files.gamejolt.net/0rIiuogMNPgptEgKpH_FXQ==,1641952679/data/games/0/172/53422/files/558df7dd04e30/Five-Nights-at-F___boy%27s-Final-Mix.rar

I think there should be an X category for Zero's Arm Parts any% and 100% or normal 100%
