Cursors made via Aseprite shows up empty when uploaded to site

So, I looked at the files and they are using the 32bit RGBA bitmap format, but have the alpha channel of all pixels set to 0 = completely transparent. This is incorrect.

Now, it appears that Windows has a workaround for this problem and detect this invalid state and ignores the alpha channel for images that would appear completely transparent. I have checked this by manually changing one byte in the file to make one pixel non-transparent and indeed, Windows showed an empty cursor with just this one pixel.

This web does not have this workaround and I will not be adding it, I do not want to help spread invalid cursor file.

You can possibly export the cursors in some other format and convert them in the cursor editor or inform Aseprite authors about this problem and maybe they will fix their export function.
