In version 18w49a (and the previous 18w48b), the /locate command would give out EndCity locations with coordinates in between Center Islands and Outer Islands. (The End Gateways are not working, all of them - Center and Outer Islands - teleport to Obsidian platform) After travelling to coordinates roughly around -3100 and further, the /locate command will not find End Cities with coordinates more negative than -3100 (both for X and Z coordinate).
