Before I go into my list of issues here I've encountered, here is my info:

Build: 497449
Protocol Version: 137
Build Date: 2017-09-22

My game World (Seed) was transfered from an Xbox 360 and was a small world size. I expanded it to a large world size once transferred to my Xbox One.
The issues I've encountered are the following:

1.) Ender chests appear as regular chests, but the ender chest particle effects are still present.

2.) Mobs named lose their name upon selecting "Save and Quit" then reloading the game world.

3.) World Chunks disappear when in boats, causing the player to be trapped in water and suffocate.

4.) Auto Saving icon shows on screen but game never saves. I created a new map and revealed the entire thing 7x and chose "Quit and Save" and upon loading the world again was back to the previous save again.

5.) Save file shows screen from last save but does not load to that location.

6.) Boats disappear from inventory randomly, sometimes disappearing while being used leaving the player in water or on foot.

7.) Transferring old worlds that are small fails. Gets to 2% then crashes the game.

8.) Trying to exit the game via the Xbox home button on the controller causes a 0x80040200 error, and the console is stuck trying to reach the menu and repeats the error until the Xbox One is hard reset by holding down the power button for 10 seconds. This error also causes apps to not ever open on the console, including youtube, Microsoft edge, and Twitch, until the console is hard reset.

9.) Grass shows up growing on sand, causing it to die and drop seeds, creating more artifacts lying around in the game world which creates lag.

10.) Transferring an old world causes a 0x8027025a error and crashes the console requiring a hard reset.

11.) World Chunks do not load, causing the player to see caves and areas below the surface.

If I encounter any more bugs I'll report them.
