itch.io

It is, it's just a bug. He said in his video he would fix it soon

ok, thanks'. a while later the file vanished (I mean I literally watched as it suddenly  disappeared) so it's ok now.

I downloaded and when I went to put it in my extensions folder my pc said the file did not exist on my desktop, despite me dragging the file from my desktop into the folder. I also cannot delete it for the same reason. So now the file is just laying there on my desktop, very annoying.
