I've been trying to make a completely empty End world. I've been developing this plugin in 1.15.1 and everything went well. But when I ported it to 1.15.2, my empty world(s), when they first generate and the first time I join it, I would crash the server. It eventually kicks me for flying since I'm floating in mid-air, and when I try to rejoin, it just gives me "internal server error". After I restart the server, every subsequent time I enter / exit the world is fine. I think I narrowed the issue down to the ChunkGenerators that I've been using because when I remove the generator, it no longer crashes. Here's the code for actually making the world: https://hastebin.com/opifedowig.java Here's the code for the ChunkGenerator that's supposed to make an empty world: https://hastebin.com/yiwunawiva.java And, here's the error / stacktrace that I get when I first join the world (I'm using Multiverse to teleport to it in this case): https://hastebin.com/lemuzozuzu.md [Note] And while I'm at it, since I'm trying to create an empty End world, is there a way to prevent the Dragon from spawning? Right now I'm just sending it to the void and killing it, and then removing the portal afterwards, but that's a "quick and dirty" fix. Is there a better way?
