The map was created in version 1.21, and there are no issues on that version. In fact, I don't think I ever upgraded to 1.21.1; maybe I should try upgrading to 1.21.1 first.  
I have never used any plugins or datapacks.  
The map has cuts because this world is a regenerated version where I moved parts of the original problematic world into this map. The original map was quite large, so I couldn't upload it directly, but if needed, I can provide a simplified version with other chunks removed.  
Finally, thanks for the reply! I can try clearing the eggs or the dispenser before upgrading.

I found how this happen its mostly related to projectiles and dispensers.

Ok in that map i found a issue.. but need know:

• In what version was created the map? and for what versions pass? (1.21 to 1.21.1 to 1.21.2?)
• In any moment you use a mod/datapack in that map?
• The map is the normal you use? i notice a few cuts in the world then not sure if maybe its more a map breaking rather than a spigot bug

Currently the issue are eggs fired by the dispenser by the chicken farm in that location i need check if the issue is the dispenser or just the eggs.

I conducted a more detailed test again and found that there may be an issue with the -1 and -1mca in the entity.
I directly created a new service from scratch using version 1.21.3, but when I added entity's -1, -1mca and region's -1, -1 at the same time, I would encounter problems if I stayed near that coordinate for a while.
I used the PCL2 launcher for testing, and previously someone on the server used the official Microsoft launcher, which caused us to encounter a problem.
Here are the main world files and error logs from my testing:

world.7z disconnect-2024-10-24_21.32.24-client.txt

Can you provide a zip with the world, also you are using vanilllla client or a custom client? if you get kicked with a error the launcher tells you about a directory to get a file with detailed log.

No issues at that location with those chunks for me

Thank you for your reply.

I didn't use the plugin.

The bug will happend Near the -256 79 -433. Located in the main world. I've placed the relevant files below; is it okay to send the map this way?
server.properties

r.-1.-1.mca
r.-1.-2.mca

Are you using mods? Can you provide a copy of the map and coordinates?

I cannot replicate this.

Can you provide the server.properties and the map? also you are using any plugin?
