So I can get the world file for you but it's kind of big and you need a computer with serious ram for it not to go bananas but it still kinda does on mine.

So thanks to a ton of patience and task manager I was able to meticulously map out the chunk radius that was causing me grief. There is an outside stone circle ring. If I go inside that stone ring for even one second my RAM shoots to 14+ GB often much higher. It usually settles down after awhile until I leave the area and come back to the ring which was the painful process I had to follow to map this out.

When I finally turned up my render distance I noticed that there was those couple of chunks that appear to be in the middle of the ring that seem to have an extraordinarily difficult time loading. I'm wondering if this is maybe a chunk error issue and is causing the game to absolutely lose it's mind. It's out of my simulation distance and render distance when I turn it down but no matter what when I cross the stone circle my RAM shoots. It's symmetry definitely hints to me that something in there is causing the hiccup. I tried to get the world in UME but it throws a fit and crashes.

Please if you have any information let me know the world has been crippled for awhile and I finally had the time to go through and monitor where my ram kept freaking out.

On a side note I'm kind of impressed that I managed to trace out the problem area
