Description
Expected behavior
It should have safely generated normal blocks following my server's packets, because blocks elsewhere on my server were normal
Observed/Actual behavior
But....Okay, look this then you can know the problems

Steps/models to reproduce
I think this is a completely random error, because most of my server is normal, including the error map I showed has been generated on the Paper server and copied to Folia, but Folia is still in the wrong state
But I observed a problem, at first Folia did load the maps normally, but as the loading maps got bigger and started to freeze from a certain edge, the maps started to get strange and made the normal loading maps wrong, which happened in the ocean, including the rivers along the oceans
Maybe it's an issue with my packets, but I can't 100% guarantee that this is the case, because the rest of the maps on my server are complete and error-free, so I chose to give you feedback

Research direction
Start by reviewing the attached screenshot and paste log, then reproduce the issue on Folia git-b97116b with the reported Minecraft 1.19.4 setup and compare behavior with Paper. Investigate whether larger map loading and freezing near an edge correlate with incorrect ocean or river blocks; done means normal blocks are generated consistently from the server's packets.
