A new world created in 1.19.51.01 has an issue running on the minecraft bedrock server where structures that are visible in the distance disappear as you move into the chunk. Once the chunk has loaded and the structures have disappeared it will remain that way forever.
If the same world is loaded locally on version 1.19.51 the structures load normally and remain.
If if the file from the server is moved locally the structures are still missing
If the file from the local copy with the structures visible is moved to the server the structures load correctly.

The problem is that the server does not spawn the structures. So now instead of the client seeing structures in the distance and the server taking over the generation, now there are just no structures at all.
Hi
Would it be possible to record and upload this issue occuring? If it exceeds file size limit you can use OneDrive or similar file hosting service and share link.

I've put together a little Twitch vod to show off the bug on my Bedrock server. This particular world was started when 1.19 was released last June and I moved it to new hosting in my effort to troubleshoot this bug. Timestamps of relevant examples below. https://www.twitch.tv/videos/1718998950
Start: General examples of terrain not generating
17 minutes - Pillage outpost generating and disappearing
20 minutes - Ruined portal and village disappearing
23 minutes - Village disappearing
Hi
What are your settings for server view distance, in game render distance and if possible PC/device spec's? Server spec's also if possible.

Tested the bug with an ancient city. This was the error.
842 ERROR] [Structure] Couldn't find a start anchor named "minecraft:city_anchor" in the structure pool element to place at Pos(-9504,0,8144).
Found a way to fix the bug. Need to go into the app data of minecraft and copy the base games behavior pack folder. Then replace the servers behavior pack folder in the with the one from the app data. Worked for me anyways. Structures are generating again
Eigther way something is messed up with the behavior pack folder for structures that comes with the bds software download.
An update from my SMP and some possible insights from my experience. The recent reports to this issue confirm my suspicion that this issue has to do with files/database being updated wrongly, or, missing and corrupted files from updates causing issues.
We got frustrated with the lack of progress on this problem, so out SMP started a fresh world in early April 2023. I asked players to stay within 1000 blocks of spawn, so we could enjoy the new 1.20 biomes closer to spawn when the game got updated.
Right before the 1.19.83 update, we started seeing an old Bedrock glitch again, which I first reported here in 2021. The glitch with the repeating sunsets. Basically the sun would keep resetting the closer it got to dusk. This problem went away with the 1.19.83 update. This seems to confirm that just updating the core game files resolves that problem. (We don't use any mods). I also wait now 5-10 minutes after a server upgrade, to make sure I don't join the server before the upgrade process is complete.
I've only seen this disappearing structure issue once since the upgrade to 1.20. I was boating around, mapping the new terrain. A shipwreck that was partially above water disappeared as I got close, but this time it was replaced by a new shipwreck that was totally underwater. New POI had loot and looked "normal."
This shipwreck may have been in a chunk generated during the 1.19 phase of the server. It's in a border zone between old and new chunks.
The only related issue we are dealing with now is terrain not totally generating (or rendering) when players re-join the server after some time away. I usually just exit and rejoin. The rendering in 1.20 feels much improved.
To follow up, after seeing Thomas' comment, I confirmed that I was able to download my world from my BDS server and run it without issue locally in Win10. My appdata folder did not have a customized Behavior Pack, so I was unable to move it to my BDS server per Thomas' fix. However, I had another server that hadn't been kept up to date, so I installed BDS for 1.20 and imported my world to that server, and was able to confirm that the problem DID NOT occur. I was able to discover a new village and a new ruined portal. My best guess is that something in the many upgrades got corrupted but by starting fresh on the server side, it fixed the issue. Still testing to confirm, but so far it looks good.
My local game did also not have files in the behavior pack folder. I locally backed up the behavior pack folder from the server and deleted everything in the behavior pack golder(thinking if all else fails I can just put the copy back).
Restarted the server and bds reinstalled all the files for me.
Bug is gone generation is back to normal.
I also believe the files got corrupted in one of the updates.
I've been noticing this behaviour too, and from what I can tell is it's to do with client chunk generation differing from that of the BDS server.
Playing on a PS4 for example, I see lots of random effects such as this when exploring a world running on a server, where distant chunks as I get closer appear to regenerate differently when closer, and from that point on they remain static as they generated. I see this less on other platforms (Switch/PC), but it is still there. It feels very much similar to both MCPE-162424 and MCPE-39439.
Setting the server option
seems to completely eliminate this, however you will then run into BDS-17527
There seems to be a few other tickets about this same behaviour too (BDS-17953 for example)
