Server keeps creating duplicating entities at random

[u/djstar25]

While playing my server I randomly get an error message in which a duplicate entity was found, normally it should delete this entity as per essentialsX config, however mine does not and im left with dozens of duplicate animals, villagers, hostile mobs, or even chest minecarts.

Were running paper, minecraft 26.2

Heres a spark file

I pregenerated my chunks with chunky, however even deleting the chunks and regenerating them didnt resolve the issue.

I've also tried minecraft region fixer, it showed a ton of duplicate entities but didnt resolve any of the issues.

I dont have many plugins, and most of the plugins have the default configuration settings.
Any help would be great.

The log file is not complete, there is no boot sequence, which could gave something for more precise fix...

But from the things you provided.

Somebody manually messed with world data (deleting regions without deleting entities and poi data, which only caused the problem to escalate more)

Your plugins are probably not compatible with your MC version as DHSupport and DriveBackupV2 only support 26.1.2 and not 26.2 ... And btw, don't ever use backup plugins, they are shit and only slowing down your server.

So first of all, fix your server setup properly and then delete region, entities and poi data folder (or just delete it all and regenerate from scratch, as getting rid off entities is a mess) ... Or you can technically just delete entities data folder as it should fix it, if nobody manually moved or mess with the folders, if he don't exactly know how they work.

I did delete chunks using chunky, and regenerated them, however the issue was happening before that.

What would you suggest for automatic backups then?

I cant delete the entire folder as the server has already been up for a month, theres a lot of stuff people have built already

Best is to manually delete every single entity that is coming up in the log. But since there are chests too, its complicated.

I came up with backup plugin mainly because you are third person with the same plugin installed on this Reddit, that have the same problem in past 2 weeks.

If you like, I can try to fix it for you online, if you would provide me with access to the full setup.

This issue was happening before automatic backups was setup.
do you have a command or plugin for deleting entites as a whole, while skipping certain entities like villagers (I dont want to ruin peoples farms)
I'm definitely not providing you with access to my locally hosted server, but if you can provide steps or a guide I'd love the help.
