I am able to play totally fine in singleplayer minecraft. My world will save fine when having autosave doing what it's suppose to and exiting the game saves like normal. The most unusual thing happens when i am playing with friends and have been experiencing this issue since 1.17 and assumed it would get fixed at some point if i just wait on it.

The past few times, i would run around in my world with my friend wanting to continue building in our world, explore the new updates, and doing whatever else to pass the time. The first time i experienced this issue was when i had a wither in my world destroy terrain, after defeating him and leaving the area and heading back to that same area, the terrain would be like if the wither wasn't even there at all, like if i never even spawned him to begin with. I have also noticed items in stashes would remain and duplicate if i just reload the chunks by entering and exiting the nether and/or the end, almost as if the chunks were overloaded in a sense even though i haven't done anything besides put a chest down with some stuff in it.

Alongside this, exploring the world is also heavily limited, as if i go out far enough, chunks world eventually cease to load entirely no matter how long I'd wait. If i enter another dimension after experiencing this, id be stuck on the "loading terrain" screen until i close application.

This seems to happen randomly and i tried to purposely cause it by retracing my step in my worlds when it does happen the first go, and it weirdly enough wouldn't happen the second time. It would also happen on any world I'd play on, a 30 MB world or a 300 MB world, an old world or a more newer one, even a world that was converted from editions for the few who have played editions.

This bug i'm dubbing the world revert reload bug has been giving me issues for a while and it drives me to not wanna play Minecraft, especially multiplayer when i absolutely enjoy playing with friends.

I'm hoping something can be done about this or i can figure out why it's even happening, as i love to play with friends in multiplayer minecraft and don't want that option being unplayable and broken were anything we do in the world wont matter cause it will get reverted anyway.
