Hi! I don't have deep knowledge about how to program the configuration so that everything updates automatically and doesn't require deleting the config for everything to be generated correctly.
Sometimes I add new parameters to the config without needing to completely delete it, since they are added by default with the value I assign to them.
The issue with this update is that the list of items downloaded from the server (internet) contains 2 new parameters for each item. If you don’t delete the existing config, these parameters won’t be added to your configuration, because those "items" already exist and are automatically ignored as it moves to the next one. In other words, when you click the blue button: "Check Update", the downloaded list doesn't overwrite the entire items section of the configuration — it simply adds new items if any are found. And it doesn’t overwrite everything precisely to reduce hassle when new DLC skins are added — especially for administrators who modify permissions or similar.
That said: This isn't a critical update — meaning if you keep the previous config, everything will still work fine. You can update it gradually, or simply add the new parameters to your current config and then upload that copy to all your servers. I don’t know what you modify on your servers, but if you have several, I’d recommend updating one first, checking what changed, and then uploading that copy to the rest of the servers to streamline the update process.
