The Alolan Exeggutor WatchTower is just a meme, I added it for fun so its not really meant for regular game play. The only performance issues I had with the world was when the tower was first built, my computer isn't vary powerful so it had to think (go unresponsive) for a few seconds. After it was built, my world I was testing it in ran fine (the sight almost fills a entire small world =) ).
