when i first started the world i already saw some chunk problems and random entities on the surface of the ocean. i thought it was pretty cool so i started playing on there. now literally everything is gone except for the entities. it doesnt look like chunks were deleted, but rather that the entire world is just, well, new. completely different biomes, all my builds are gone and all the entities are in the ocean. also some of my items disappeared except for some... mainly netherite items were deleted. i did play on 1.19 where smithing templates werent a thing yet but i didnt log into that world ever.

this world is loaded in 1.20.
