So i go to load an older world, around 2200 days and it loads for about 20 seconds then crashes. All my other hosted worlds open fine. The only difference is Wurt. Wurt has not been played on any other of my worlds. But in this world someone built me a murm area complete with murm King and flortifications and murm houses. Thanks i hope this helps.
Steps to Reproduce
Try to start the world
