Had To delete stuff due to word limit sorry if i deleted anything importaint

That's why it's recommended to attach the text file to the ticket, rather than including it in a comment.

Does this only happen in a specific area or world? What is the area like where this occurs? Any redstone devices? Is it near the spawn chunks? Can you zip up the world and attach it to the ticket, or upload it somewhere and provide a link?
