1. The picture issue is me being silly :( to bypass it, copy an image in the img folder and paste it. Change the name to match and it will clear the error. I.e (copy Nina6 and rename it to Nina7)
2. that one is bugged. It will cause a freeze at the moment. I would avoid using it for the time being.
3. That stuff is on the Patreon version only at the moment. Not in the demo.
