This has happened quite a few times now, I have a bamboo farm and a sugarcane farm with rails running underneath and hopper carts circling underneath the blocks where the items are planted. I have looked through all the hoppers and chests and they do not show up there, there have not been any creepers that have blown the area up, they just vanish. I am not sure if it has something to do with the circle pattern of the rails but in another part of the world I have a similar system to catch mop drops under a zombie spawner and the carts do not disappear, in this instance the carts bounce back and forth on straight rails.
Clients connecting to the world are:
Xbox One X
Windows 10 1803

This isn't a duplicate, the game isn't crashing or being forced to crash. I always exit cleanly..

Additionally, I am not anywhere near the chunk when I exit the game.
Thank you for your report!
