I haven't checked back with this thread for a while until now...and I'm confused, too.

It seems that I forgot to set the permission of editing the folder I shared and someone has messed it up. Now I've cleaned up the folder, re-uploaded the dark theme, and set the permission that it can not be edited by others anymore. Hope this would help.

I have to generate a new download link in order to change the folder permission, so the original link shouldn't be working any longer.

Here's the updated download link:
