Your right. It doesn't modify the game. But if you load the seed in a single player world, you can get the coordinates of where all the diamonds are. Because the world is the same always for the same seed (and same version), you can just go into that server, go to the exact same coordinates, and the diamonds would be found there. So pretty much it is cheating, if not, worse than x-ray.
It wasn't my original comment... Somebody said it here in this github: https://github.com/PaperMC/Paper/issues/3654
It did fix some people's issues though, so I don't think it doesn't work.
@qbdown i heard in paper if you set these settings:
async-chunks:
enable: false
threads: -1
the problem will go away. However, this is only a temporary solution, because you should switch async-chunks to true after due to it optimizing chunks better.
I'm particularily surprised of the performance difference especially between 1.15.2 to 1.16.1. It seems before my server computer wouldn't lag, and it would stay at a solid 20/20 TPS. After the upgrade, it seems that everything lags. TPS drops to be around 10, (and can even reach 5). Loading new chunks take a good amount of seconds before they render. Also, saving the world for me gives me another error saying "my computer was not strong enough to handle saving the world" which a couple seconds after, the console said I saved the world. The computer also freezes a ton, which was not something I commonly saw before.
Could you send some images/videos to show us this is happening? If you could also tell a method that shows how to reproduce the issue it would be even better.
Is there anyway to fix this issue? I suppose we can open the world in a program like MCEdit and regenerate those chunks, (maybe that will help). Seems that at first join Server TPS drops very low, maybe around 5-6 TPS. After the second join onto the server, TPS goes back up to 20.0, however console spam and errors are still there. Seems to be a major issue that should be prioritized.
Hi, I would also like to throw out that this error also appears in Spigot servers.
Are there any admins or mods which can help us find a work around for this issue or will let us know that they are working on this? Thank you.
