How to make Lost Cities map for paper server:
Install Lost cities mod in neoforge (i used ATlauncher, will work with any), install mod Chunky
Create world, pregenerate chunks with Chunky (radius 5000 give map size about 4.5GB)
Then install Chunker and convert that map to vanilla, which will work with paper server. That's it!
