//EDIT 01.11.2018
A download of the world can be found here: https://www.dropbox.com/s/wrk5j2y5q92kh4t/World-1-12-2.zip
Note: Unnecessary chunks (chunks not near to the world spawn) have been removed with MCEdit.
The issue occured exactly as described above with the pruned world available for download, when loading it directly in 18w44a.

And a second crash occurred after loading the world again, after a few seconds in game with the same cause
//EDIT 01.11.2018
A download of the world can be found here: https://www.dropbox.com/s/wrk5j2y5q92kh4t/World-1-12-2.zip
Note: Unnecessary chunks (chunks not near to the world spawn) have been removed with MCEdit.
The issue occured exactly as described above with the pruned world available for download, when loading it directly in 18w44a.

Changed Description:
Opening a 1.12.2 world in the 18w44a snapshot causes the terrain to be regenerated, replacing already existing blocks (placed by player). This is how the world is supposed to look (screenshoted in 1.13.2):
And this is the world in 18w44a (loaded from a backup saved in 1.12.2):
Opening the world in 18w44a caused a crash before the world was loaded the first time:

Thank you for your report!
However, this issue is a Duplicate of MC-138547.
If you have additional information, please add it to that report.
Please search before reporting, as it's likely that one exists already.

Seems like MC-138547.
This seems to have been fixed when MC-138547 was fixed. I opened the world in 19w04b and all the chunks loaded correctly.
A few of the chunks were swapped though, but that seems like a different issue. Even when opening the world in 1.12.2, I got the error "Chunk file at 15,11 is in the wrong location; relocating. (Expected 15, 11, got 14, 13)."
Thank you for your report!
However, this issue has been temporarily closed as Awaiting Response.
Do you have a backup of the world from an earlier version (preferably 1.12.2 or 1.13.2)? If so, please attach (or provide a download link of) the world here so we can reproduce the issue.

Confirmed when upgrading from 1.12.2 → 18w44a.
Based on what I have observed, any chunks that were last opened in anything earlier than 1.13 final, seem to get regenned or at least messed up by 18w44a/18w45a. Any chunk opened in 1.13 final or later, will not get regenned or messed up.
Right now, I saw a chunk load fine in front of me, and then get regenerated.
I has having a very similar problem with a super flat world. I ended up going back to 13 final and combing over everything before updating to the latest snapshot just to be safe. Seems to be working fine now, but it took a dozen or so tries.
Please do not mark unreleased versions as affected.
You don't have access to them yet.
Similar to what João has noted, I can add that a 1.12 generated world, updated to 1.13.2 and then opened in 19w02a, exhibits the same behaviour where the 1.12 generated terrain was unexplored in 1.13.2.
It seems that 1.12.2 generated terrain that is re-visited in 1.13.2 remains unchanged in 19w02a, but exploring outside of this causes world regeneration, leaving only blocks placed in what was minecraft:air in 1.12, to be left intact.
Seems to load without extra generation on latest snapshot, can you confirm on your side?
I can confirm that generation seems to now work as expected in 19w03a. A 1.12 save opened in 19w03a, using both the "Optimise World" option and without (done on separate copies), the generation is as expected. Hopefully the OP can confirm also.
Yes, I can confirm that is fixed with 19w03a. I must have forgotten to remove the old copy of the world before testing with the new snapshot.
