making a world doesnt involve the AI at all, are you sure you are using the World Editor and not the gameplay part?
Sadly yes. Though it seems to be a connection time out problem as if I refresh the page, in a duplicate tab, it saves the world edits. Is it also possible for you to make it that I can download if the page doesn't refresh. Your game is my favourite and I'm enjoying building a world to play in and it's sad when it fails to save the world
