Minecraft worlds on ps5, when reaching 950mb, tend stop opening entirely. They get stuck on the loading resources, then just said world cannot be opened. But a fix where you transfer the world to ps4 and then back to ps5 works, but is very unreliable and makes the world prone to crashing. Also multiple chunks were replaced in and indefinite line across the y axis, and this occurs from 100-200 blocks apart, to about 5 blocks apart, which makes my world look like an absolute mess, but I was lucky enough that not too many builds were harmed, but I imagine many who encounter this bug won't be so lucky. These also replace entities, too. I also noticed that all world space after the bug goes into a separate file, which is a bit odd. Also I don't know what version this bug occurred in, but this is the only one I can choose, so sorry about that.
