The situation is this: The other night I returned from the End. My last bed had been broken, so I returned to 0,0. No problem, I'd just go back home through the Nether Portal in my first base in Minecraft...
Except a whole bunch of chunks in the vicinity of spawn, including my first base, have somehow been reset.
The most recent backup I can find that still has my first base in it is from May, so I can't just revert to it. But since I'm still playing in my first world, the missing base is the first base I ever made in Minecraft and losing it makes me sad.
Is there a way I can copy those chunks from my backup world to my current world, in either 1.14 or 1.15? I know I could just copy the whole region file, but that's going to overwrite a fairly large area: I don't THINK I've made any changes in that area since May, but I would feel better if there were a way to copy smaller sections including just the smaller area around my first base. Other suggestions I have seen include MC Edit (but those are old suggestions -- MC Edit won't work with 1.14 or 1.15) or structure blocks (which I may try but the area they cover is too small to be practical to fix more than just the base itself -- the area around it will have to stay reset).
Aside 1: Has cave generation changed since 1.7ish (I think that's when I created this world). My recollection is that I built my first home in a natural cave entrance (there is certainly a cave entrance there now in my old backup world) but there is no cave entrance there in the reset area. And I found an old entrance I'd marked outside the reset area. I went in and when I reached what is apparently the boundary of the reset area, the cave just stopped. I dug to a place that I know was a natural cave in my old backup world, and there is no cave there. The exterior terrain looks basically the same but the caves seem to be different.
Aside 2: Anyone know what could have caused this? It's many chunks that have been reset, not just one, but it doesn't seem to be the whole area covered by the region file.
For chunk copying, might be done using mcedit, or take some structure blocks, save the chunks as structures and copy their files on the other world

Descriptions are in french, you'd just need some google translation copy-paste...
Also made some more or less complicated datapacks, shared here (planetminecraft).
For your second question, cave generation changed in both 1.7 and 1.13, the latter of which also changed the locations of many structures (apparently Mojang doesn't think that changes like this matter; I'd consider changes to caves to be equivalent to large-scale biome changes given how I play). Smaller features, like trees, ores, and passive mobs, change much more frequently but these usually aren't important unless you are using a seed with a specific feature (e.g. pink sheep).
As for why this happened, 1.14 and 1.15 have some issues with world corruption, though this has been reported in any version, particularly if you ever had the game crash or you quit abnormally (I've never experienced issues like this in 1.6.4 except when intentionally replicating them; at least one cause has to do with singleplayer running a server on a separate thread and the client not properly communicating with it when quitting, which I fixed myself, this probably isn't the only issue in newer versions though):
MC-161823 Chunk corruption in 1.15 (this is really the same issue as the one above, incorrectly assumed to have been fixed. Note that both of these refer to chunks being misplaced, but not reset, but that could be happening as well)
As for a fix, you could try making a backup of your current world (the corrupted one) and replace the affected region files and check to see if you replaced anything you didn't want to (use this tool to determine which files need to be replaced); otherwise, the options are quite limited given the lack of tools like MCEdit, unless somebody has made/updated a mod like WorldEdit to 1.15, and I'm not sure what its limits are.
That would be the 1.13 update that changed my caves, then. At least I'm not imagining things! On the bright side, I now have part of a shipwreck poking up out of water right in front of where my first home used to be, which is kind of cool. Maybe I'll just use structure files and then see if I can dig out an opening until I connect to a cave in the new cave generation.

Hey, I've done this in the past but now in 1.14.4 I'm not getting the past option when in the chunk node, even though NBTE lets me "copy" the healthy chunk from the backup world...

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.

Why do I still play in 1.6.4?

You can copy and paste individual chunks with NBTExplorer.exe
NBTExplorer install:https://github.com/jaquadro/NBTExplorer/releases
https://minecraft.tools/en/coordinate-calculator.php Will, if given the coordinates of a spot in a world, give you the region and chunk that location is in.

I've tried that and when I try to "paste" I don't actually get paste as an option. It's strange.
In MCEdit or structure blocks?
I don't know MCEdit that much as I'm not in mapmaking at all but structure blocks have "Load" option for loading a structure in the structures folder.
Here are some sources :
Structure blocks :

Map editor list (maybe something better for this than MCEdit)

I'm getting the same problem - did you ever solve this? Thanks : )
