Chunk Swapping

When has the world been created? And what exact version are you playing on?

i created the world yesterday and im playing on the latest snapshot 19w35a  i created in 19w35a too     fully 19w35a

Hmm. Can you share your game output log with us? You can find it in [minecraft/logs|http://hopper.minecraft.net/help/guides/finding-minecraft-data-folder/]. There should be multiple files in there, one for every time you played Minecraft. Please attach all the files from when you played in this world.

Also, it would be very helpful if we could take a look at your world save. Please attach the affected (zipped) world file. If the file size is too large, please upload it somewhere else and then link to it here.

i attached the world logs      and the world link is here  : https://www.mediafire.com/file/ocqesap1qzui1t5/UltimateSurvival-1_15_19w35a.zip/file

Thanks a lot! The file from when the whole swapping occurred is this one:

Do you have any anti-virus? Also, did you crash before world was corrupted? Was your drive full?

i use windows defender  and i dont think it crashed so far i can remember so not 100% sure

i think my computer got shut down because the power went out thats probably it

In that case, there's not much we can do about that issue. If a world cannot be properly saved and gets corrupted in the process because the Minecraft process is killed, Minecraft itself cannot prevent any corruption.

If the issue occurs again with a new world without the computer being shut down while Minecraft is running, please create a new ticket.

Okay im sorry for taking your time
