Chucks missing and loading incorrectly near ocean biome

After creating a backup I opened up my world for the first time with 1.13. Many ocean chunks are missing and some chucks are switched with surrounding chunks. There are huge holes in the ocean. It allows me to see through the ground. It wouldn't let me walk into the missing areas. In some chunks you can clearly see particles and entities while others are completely blank. I tried shutting it down and reopening and it did the same thing as before. I tried opening the backup, but it also had the same glitch. The areas affected are all ocean biomes or next to ocean biomes. The other worlds I opened with 1.13 have no problems, even the one that is a copy of the world with the bug. This world is from 2016. it was created before 1.10 came out, but after 1.9.

Is this still an issue in 1.13.1?

Yes, it is still an issue in 1.13. I tried to load my backup as well and it's still corrupted. What should I do now?

Please attach (or provide a download link of) the backup here so we can reproduce the issue.

Can confirm. The world struggles immensely when trying to load that area.

The world is likely corrupt; upgrading from 1.12.2 to 18w44a results in a lot of chunks regenerating. Upgrading from 1.12.2 to 1.13.2 to 18w44a does load the area, but swaps a lot of chunks around.

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)."
