So to prevent island farming, I think we should add this. This picture was taken on mineverse. Thank you Mai for getting this idea to my mind.
Support, but 395 seconds, hence 6:30 minutes, is far from being enough. Maybe I'm extreme, but I'd set this on 1 hour IRL! I think on average you Play at least on hour on an Island before noticing your built goes the wrong way so you'd like to start over again. And this surely makes the little bit of dirt and sand on the Island way too pricy for Island farmers.
