This may be a duplicate of/related to MC-184907 - same error during the crash. It may be taking a moment to load the chunk causing the error. Does the game crash whenever you mine that particular block, and remain running if you mine around it, or does it crash anyway?
MC-184907 indeed.
Likely a duplicate of MC-184907, considering the new crash reports.

MC-184907 - this was fixed in 20w22a, please update your server.



Does it only happen in this one specific world, or all worlds?
I have not noticed it yet in another world. That world was created in this snapshot and it was several hours into it before it started crashing. That world now won't play for more than 10 minutes now without crashing. I am testing others, but like I stated it was several hours into it before it started acting up.
Did you use any special world settings? if so, please attach them here.
Nothing. I did use the seed of 'takingalongbreak' but nothing else. There first time it happened, I don't remember what I was doing, but the consecutive times I had a lead on a donkey and was walking it across the plains. The donkey did have a full chest of items on it.
Oh, I do remember the first time. I died, and when I respawned, it was like it put me somewhere else like it wasn't the same spawn location as when I started the game and I couldn't get my bearings. Then the game crashed and when I launched it, I had all my stuff, plus the when I went back to where I died, all my stuff as also scattered across the ground, so I ended up with duplicate items of everything I died with.
I got this crash on a customized world, and it appears to occur consistently when I go towards a particular location on that save. However, after re-creating the world, I cannot reproduce the issue. It seems that the location I am heading towards is a village, and the game possibly crashes when the village is generated.
Same crash happening to me. Server that we created with new snapshot. After several hours we crashed several times. Was able to figure out it was on a specific player logging in that triggered the crash and teleported them on login which prevent the crash for another 5 minutes.
We were near a village when we crashed. The map was new and the original person who crash was just walking through the planes near the village. The village had been looted and played in for a little bit, before the crash happened just outside of it.

I uploaded my world at https://file.io/Fw9KAZiR if that helps.
I was headed to a village too... that might be the clue. My donkey and I are at 121, 71, 44.
Thurman Jenner That link doesn't work for me.
Let me try this again. This one will keep the file for 1 week instead of a matter of minutes. https://filebin.net/6yx2pmj1xn0a93kl
I managed to reproduce with that world file. I was heading in the south west direction.
Can confirm, I was able to reproduce this multiple times. Strangely the first time there was no crash report generated. The second time occurred around X: 1500 / Z: 9500 on seed 7710288261028957899. Archive with the world, log and crash reports, and also the first log without crash report.
VideoklipBG, one of my original crashes also did not generate a report
I just got this same error in ImmutableList.sort(ImmutableList.java:565) twice.
Seed shortcut is "20w21a" - I still use unique worlds for snapshots.

I didn't did anything special on my world, only surviving and nothing else, no worldedit or anything else.
I think I am also experiencing this bug. My vanilla single-player survival world, created yesterday (24/05) on the latest snapshot with no mods or adjusted settings crashes when approaching certain chunks in a plains biome bordering a taiga. So I think there's a good chance the featured placement is due to a village attempting to load in. Attempted to approach from three directions and all caused the same crash. Initially, I was riding a fast horse and my laptop is quite slow so the FPS was dropping below 10, just thought I'd mention it in case that would affect the generation. Maybe also worth noting, each time I reload the world I am back in the same place I was right before I tamed the horse, a couple of hundred blocks south of the broken chunks. Each time I have to re-tame the horse, but the areas I had previously explored on the horse were still visible on the maps I was holding, even though the game had reverted to a point where I hadn't yet actually explored those areas. Hope this helps.

Also seeing this in a world that was generated prior to the most recent patch imported into it.
Like jack the game resets to a point a bit before the crash or the latest save however, when I was mining I was actually making progress even if I lost the cobble after each reset.
I assume map data is being saved correctly but not player information.

I had a similar issue whilst flying through a cave in creative. The world was freshly created in that particular session. [^latest.log]
Having this problem when traveling long distances on an ice boat, I tried to inspect the surface to see if anything by the crash site was wonky and found this village

Seem to have had the same issue on 20w21a, running on a Ubuntu 20.04 Server. When getting too close to the tiaga village the server would crash, the game also crashed when I downloaded the world and played in single-player mode.
my seed is 681878832968391 and resolved by deleting chunks (12, -53 to 15, -56) using NBTexplorer.
This world was created new on 20w21a, not sure why the first time generation would have caused the issue, but after deleting the 16 chunks it re-generated just fine on the server and it no longer crashes. I probably could have narrowed it down some more but didn't feel like dealing with even more crashes.
I do have access to all the crash reports and server logs if needed. The latest crash report is attached.
crash-2020-05-25_19.23.04-server.txt
Same thing here. Repeats everytime I try to load the area.
Seed, coordinates, etc.. should all be in the crash log.
crash-2020-05-26_11.48.37-server.txt
Looks like I am experiencing the same issue playing 20w21a on world with seed "20w21a":
I haven't seen a village but that does appear to be the feature that the crash report mentions. Every time I cross a chunk boundary towards an area I had not previously explored (was trying to lure some sheep towards me haha) I get a full game crash.
I will attach the crash log, screen shot of chunk grid with debug, and screenshot of error output.
Edit: I forgot to mention I noticed my video card spike to 100% usage each time right before the crash.
crash-2020-05-26_22.37.20-server.txt
I had this exact same issue. Deleting/resetting the chunks where it keeps crashing with MCA Selector or NBTExplorer can resolve the issue for now.
ive just got this issue on 21a and had to use an alt account to tp my other client away form the village cause it kept crashing the server each time i logged in
Bump, Any updates?
I own a 1.16 anarchy server and there's literally no way i could prevent it- Hope its fixed within a week.
Please don't bump. You can see on top of the ticket what the progress is.
Since snapshots are versions still in development, and as such crashes like this one are to be expected to happen from time to time. As a rule, you shouldn't rely on snapshots working flawlessly. That's their whole point.
I have the crash too when I teleport to certain villages. I saw that the generation of the villages changed in 20w21a as well as a couple pillager outposts disappearing in a few spots when 20w21a released. This may be the reason.
Based on the info from users, this has been fixed.
