To be clear, it was the Discord Overlay causing the issue. I have tested having the Overlay keybind set to Shift + ` (which makes ~ in-game but also triggers the overlay, causing the issue) and an alternative keybind (Ctrl + Numpad Period, which doesn't trigger the issue) in 1.13 pre-1.

Apologies for not providing more information or being more active about reading replies. At any rate, the bug appears to have been fixed in 1.13 Prerelease 1, so I am okay with the bug being marked as resolved. With regards to @Kumasasa's request to examine the logfile, nothing was logged, but I have attached the logfile here regardless. MC-123968 does not describe my issue, as I am unable to click back into the game to resume normal operation.

EDIT: MC-123968 may actually be the issue I had, as I just checked and my overlay key was somehow reset to the tilde key, which I didn't think to check since I had a different keybind before. I have set the Overlay Lock keybind to something else and the issue has vanished. Thank you @tryashtar for realizing what the issue might be!

Huh. That's more than a little irritating, though I am glad to hear that the behavior will be what I expected in 1.13. Guess I'll have to find a workaround for now. Thanks for the insight FVbico!

Not sure if this helps, but with a server I was hosting on my computer, I forgot to properly halt the server before shutting down, and I came back to the chunks being swapped around, as you describe. Perhaps the issue is insufficient resources being dedicated to saving the chunks in the proper location? This is just a hypothesis, as I have very little knowledge of the inner workings of Java.

More information if possible please. Was there a light level of seven or lower where the Enderman spawned? Can we absolutely rule out the possibility that it teleported from an underground cave while the world was loading?

What happens when you place the armor stand, and what were you expecting to happen?

As a suggestion to improved your bug report, what did you expect to happen/what do you think was intended to happen?

This may simply be a case of block lag. Without further information it is impossible to tell whether this is a bug that should be fixed or a machine limitations.

It would appear that any achievement hinging on building an item is currently broken.
How to Reproduce:
1) Generate a new world in version 16w32a
2) Open Inventory to give yourself the Taking Inventory achievement
3) Punch a tree. Note that this does NOT give you the Getting Wood achievement
4) Run the command "/achievement give achievement.mineWood" to manually obtain the achievement
5) Create a crafting bench. Note again that this does NOT give you the Benchmarking achievement.

And so on. I haven't done much testing, but that's the status of things as is.

Confirmed for 1.9-pre2

Confirmed for 16w04a, also the display name is not checked by the game code. What matters is that the string pointed to by container.minecart is not displaying, Marcono1234.

Confirmed for 16w02a.
