Hello. I am trying to upgrade my world from 1.21.11 to 26.1.2 and every time I do the upgrade, it is “successful” but it loads into an old version of my world that is over a month old where I barely had any progress. I have restored my world to the working 1.21.11 version and tried the upgrade again with no success. I expect the world to be upgraded to 26.1.2 with my most recent world data, but it only upgrades and loads me into an old version of the world. Any help would be greatly appreciated. The world file with the correct 1.21.11 world is attached that I would like to be able to upgrade to 26.1.2. Thank you!

Hello Baslod,
See the OneDrive link below to the 1.21.11 world file and then the 26.1.2 world file. The 1.21.11 file is the most up to date and correct version of my world. The 26.1.2 world file is the upgraded world, but it is the world saved with the bug where it lost all my progress. Let me know if you need anything else from me. Thank you!
Hello, can I get confirmation that since I added in the world files that this ticket has been reopened? Thank you!
Hi!
Thank you for your report!
However, this issue is Invalid.
Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.
Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
A world which had previously been opened with a modified client might be corrupted. Please try reproducing the issue in a newly generated world.
Any plugin issues need to be addressed to the creator of the plugin or resource pack.
If you have problems on large servers like Hypixel, please contact them first as they run modified server software.

I had the same problem trying to upgrade from 1.21.11 to 26.2. I fixed it deleting the “dimensions” and “players” folders of the world and it worked. Be sure you have a backup of your world before you try this solution. Hope it helps.
Thank you for your report!
