Somehow, likely in the last few days, the checkbox 'hide this file' got turned on. I don't know how. I've now fixed that. Sorry for the confusion.
It's also possible this has been a problem on this listing quietly for far longer, in which case it's deeply unfortunate. The files have been present on itch with occasional updates for years but if nobody was able to download them the entire time that's a really big mistake... I'll go through other listings and make sure all other asset pack files have the checkbox set correctly [just in case this has also happened anywhere else]
Thank you for bringing this up. I might not have noticed that issue until much later if you hadn't called my attention to it.
