I need help with my minecraft world. The blocks that i place or destroy wont either save or load. If i place a block, save and exit the World and then Oper it again the block that i placed is not there anymore and if i destroy a block, exit and then open the World again the block is still there. Like i can interact with the World perfectly but the Things i build or destroy dont save or load properly. The Inventory, Player location and the rest is working and saving or loading properly but only the blocks seem to have a Problem. And this is also only an issue in some parts of the World, only at some chunks the Problem seem to appear but if i tp myself a few hundred blocks away and then build or destroy something, exit and open it will work and the blocks which were placed Show up. So the Version is 1.16.4 and the World is in singleplayer creative and the issue is only Happening on this one World. The other worlds work fine. There are also no mods and no optifine but resourcepacks and datapacks but even without them the issue remains. There is even enough space for the World to save. I had similar issues with optifine and curse beforehand but i dont use them anymore and only play the vanilla Version.
And also i dont know if its an issue with the saving or loading of the World
