Issue: A chunk containing a redstone contraption reverted to the state it was in a few days ago. In the screenshots below, you can find the before and after screenshots. Pictured in the before screenshot are two double chests. The chests contained multiple enchanted tools, redstone components, and assorted building blocks.
Edit: After further testing, it seems that changes in this particular chunk are properly saved when the world is exited. See video attached.
