The problem I am experiencing relates to my storage area at around -11 y axis. The storage area was 100x100 and 50 blocks tall, completely lit up and surrounding areas all cleared out too. I was making an automatic storage sorter, specifically the recatogiser by redstone wizard on bedrock edition and was experiencing lag where chests would take upwards of 30 seconds to open, slimes in the area (very few spawning) would jump then be frozen in mid air, placing or breaking blocks would either revert to original state or would act nonexistent, eating food wouldn't register and any redstone components stopped functioning. I assumed that I had too many chests, too much redstone or something of the sort and removed 90% of it including the item elevators and input output areas as they would cause the most lag. Despite this, the lag persisted and causes the large area to be unplayable. I went through different systems like ps5, my own personal laptop and a friends laptop and the same issue arose. I tried previous save files to see if any of them had a version that would reduce lag enough for that area to be playable in. The best I found was from the 6th of December 2024, PRIOR to the winter drop update being installed on the minecraft version. I assume this is part of the problem and would appreciate any help with this.

The footage of this bug is attached in a youtube private video link showing where the chunk loaded incorrectly, it reverting to what was built in the chunk and a showcasing of the lag through unplayability. https://youtu.be/X6VpIemxecU

• Also unsure which update affected these chunks, the 1.21.51 or the 1.21.60.24 as i checked and the 1.21.60.24 was released (i think) on the 13th of december
