Cannot reproduce.

Can you please zip the world and attach it to this ticket or upload it somewhere else?

It is happening to me almost everytime I exit a world, no matter what, however apparently no information is lost and everything seems fine when I enter the next time (until I exit that world again)

This was fixed in a snapshot that I don't remember, 18w15a or 18w16a.
