Issues with moving LODs from a singleplayer world to the client-side on a multiplayer world
I can generate LODs on the client-side by flying over the chunks with an elytra, but I want to pregenerate the LODs without having to fly over them. I have a copy of the world so I opened it up on singleplayer and let Distant Horizons generate LODs for a while in the Overworld. I then moved the .minecraft/saves/worldName/data/DistantHorizons.sqlite file to .minecraft/Distant_Horizons_server_data/serverName/<bunch of random characters>@@minecraft@@overworld/DistantHorizons.sqlite. When I open up the server, some of the LODs seem to load, but are completely black. How do I fix this so the LODs are not black and all of the LODs are loaded? I don't have any issues with Distant Horizons otherwise.

Solution
Nevermind, I fixed it. The problem was that when I imported the sqlite file, I accidentally made root the owner of the file (I'm on Linux). After changing the file permission to my user, everything works perfectly.
