When I am customizing the game, when tryimg to change my name, hair style, tail style, and many other things, it says "prompt() not supported" and I can't change that aspect. How would I fix this?
Changing certain settings result in a pop-up dialog box when clicked. It is probably your computer/phone/tablet/etc. or web browser that's causing the dialog box to not show properly because for whatever reason the thing you're using does not seem to support the pop-up dialog box. I don't have enough information to give you an answer on how to fix your problem. You might get an answer on how to fix this by doing a google search about the popup dialog box not working + whatever system/browser you're using.
