 Similar issue here. Upgraded to 1.17.1 from 1.17. World spawn shifted with spawn chunks. Now we're seeing generational issues where newly discovered junks don't connect/transition properly to the previous chunks (straight line transitions for the new chunk to the old).

Can also confirm on 19w07a, java 1.8.0_191-b12, windows 10.

I haven't observed partial End Cities but rather based on generation, are simply not there. This has been the case in both 15a/b and 16a.

Additionally, the same seed used in two wor;ds may or may not contain an end city the same location. This has also been observed with /locate being able to find an end city in one world at a particular set or coordinates but then not in another world with the identical seed. Both with Generate Structures enabled.

While the items above are marked as resolved, I'm uncertain if you're saying it should be resolved in 16a as it is not.
