Hi, I am the original creator of this report. I am posting this new comment because, due to the migration of the bug tracker system, I no longer have access to my original account, even using the same email address.
IMPORTANT UPDATE: THE ISSUE ALSO AFFECTS PS5!
The severe lag spike issue during autosave is still present and is LITERALLY making the game unplayable for many users. I was surprised to learn from comments on my video that the problem also affects PS5, which indicates this is a deeper optimization or code issue, not just a PS4 hardware limitation (CPU/HDD).
Dear mods, please, I urge you to re-evaluate this issue. I am here after being ignored for 3 years because this is a truly critical bug. Most players don't even know the autosave is the cause of the freezes.
Detailed Description and Reproduction Steps:
What Happens: When the autosave runs, the local server freezes severely, causing huge, game-breaking lag spikes. As you know (per the original report), this stops all interactions: mobs, block placement/breaking, chests, inventory, and even the game ticks (redstone, day/night cycle).
Frequency & Severity: This occurs every time the autosave executes (random intervals). The strength and duration of the lag spike is DIRECTLY determined by the SIZE OF YOUR WORLD (MB/GB).
How to Reproduce:
This problem does NOT occur on recently created worlds because the file size is too small.
The lag starts and intensifies after playing for some days or weeks (depending on the amount of generated chunks/world size). The bigger the world gets, the worse the lag becomes until it is unplayable.
