Hey! In your hiddennames mod, why did it download a data.json in the world/hiddennames that is 5MB with 6500+ user entries? And it freezes the server every time it saves it, this is insane lol. I'm using forge 1.20.1, but I noticed it after creating a singleplayer world that is lags every 5 minute, then checked it out and there is was. But it seems that I cannot recreate the problem.

Holy heck it came from the multiplayer server i'm playing on

Looking at the backups the world was created without the data.json copied from the server, but after it somehow copied it. Anyway could you take a look at it, and make some changes to the onWorldSave event, because it is really computing heavy.
