I already figured out that if I create the world with the same seed in version 1.21.1 and copy the region folder into the .minecraft folder, I can recover some structures. This method may only work if you created your map in previous versions and you lost your inventory and items that you had found in 26.1. I also found out that the problem is in level.dat and level.dat_old. Does anyone have any idea? I already realized that somehow we need to modify these files, but I’m not really sure how to do it. My english is not that good so if there is something wrong I apologize.
