Please attach the file that I asked for, a picture of your screen is not enough.

Milan Vencl 2019-06-29T19:49:51Z

Is this what you wanted?

violine1101 2019-06-29T19:58:16Z

Yes, thank you.

violine1101 2019-08-03T12:35:04Z

I've been able to reproduce this crash in 1.14.4 by using the world from MC-158193. I've attached the world file, as well as my 1.14.4 crash report, to this ticket.

Can confirm for 19w34a.

Peter Silie 2019-09-05T11:54:40Z

Is it possible to have a work around like delete a corresponding region file in an older world? Not sure how we should go about this on our server

homie lizard 2019-09-23T00:38:50Z

had the same, but it was a day after i LEFT an endcity. even got a diamond shovel...

Kevin Harms 2019-10-28T14:19:49Z

Does someone have a workaround already?
My server keeps crashing too, many endcity's where generated before 1.14 and players made many things in the end.

They are able to teleport away on login if they are fast though, so its never a full crash loop, but still.

violine1101 2019-10-28T23:22:21Z

The most viable workaround right now is probably to just delete the affected chunks from the world using a tool like mcaselector.

Peter Silie 2019-10-29T10:20:13Z

Unfortunetly, deleting the chunks didn't help and was in fact not a workaround :-/

Warner Krelekamp 2019-11-22T19:23:03Z

Have the same problem here but it happens in the overworld, nobody has on my server accessed the endgame yet.

In my case the crash happens when you are near -454 65 -376

From the logfile:

[19:27:50] [Server thread/ERROR]: Chunk file at [-41, -33] is in the wrong location; relocating. (Expected [-41, -33], got [-63, -49])

[19:27:50] [Server-Worker-6/ERROR]: Region bounds : -49 -41 | -33 -25
[19:27:50] [Server thread/ERROR]: Encountered an unexpected exception

IF you want you can get the backup of the world, but it is big. The tar,gz file is 389M.

The world started with 1.12 and has been moved to 1.13 and now 1.14

Warner Krelekamp 2019-11-27T16:20:32Z

I did a test with my world on a virtual server also Debian linux and 1.14.4 crashes BUT 1.15pre2 RUNS WITH NO PROBLEMS!!

seifer44 2019-12-08T00:25:34Z

I just ran into this same problem. Only a single user was online. This is a 1.14.4 server.

I can also say i dont have the problem in 1.15.1

Chris Andrews 2019-12-21T14:08:30Z

Tested with 1.15.1. It no longer gets the fatal server-crashing exception, but the server log does get spammed by dozens of messages about invalid structure reference. I also noticed that even though I've visited End Cities before, I got the "The City at the End of the Game" achievement again.

Is this still an issue in 1.16.3 or later?

GeometricM 2020-10-02T15:10:18Z

No, It is fixed, you did wonderful job!
