it's in the OP in the halloween 2021 pack, in the BTS folder.
Also, checking for it, I noticed that the 2023 halloween archive contains files labeled as 2022, instead of 2023.
Not sure if the error is in the filename or in the archive name.
are those ai upscaled? if you want to share them it's best to split in smaller sizes with winrar or 7zip because of host limits, or make a torrent preferably seeding with a seedbox, those files are way too big
