So I am playing on a realm with my friend in survival. I have created an endermen farm. When I went back to it today it wasn't working and that was when I found out that the endermite had despawned. I am 100% sure I named the endermite. Also, the weirdest part was that the minecart had also disappeared. Why did the minecart disappear with the endermite? I am really confused. Is this a bug?
