you definitely need to at least load up a test server and instance with dynmap and chunk pregenerator mod and figure out why those screw up mineos beyond belief like they do, i tried to pregenerate my world the other day just doing a 300 chunk radius circle from the spawn point and it is literally impossible to get the server to stop gracefully with either the pregenerator or might only be dynmap, but that’s part of my start up tasks before i can play i need to pregenerate the world as well as complete a dynmap fullrender of it ideally.
