I'm getting this in my console but I have no idea what prints it: 

[00:24:03] [Render thread/WARN]: Invalid biome data received, starting from 0: [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]

I'm not creating any biomes but I am working with dynamic dimensions. Any idea what prints this out so that I can debug?

It's printing biome IDs. Show your world generation, specifically where you generate biomes. Most likely you are using the wrong IDs.

I'm assuming that biomes should be generated in the ChunkGenerator? I haven't added any code to generate biomes I don't think: https://pastebin.com/GYD8v4Xd

I would ask you just post your whole code as a Git repo.

Here, it's still very incomplete but it should all be within the common.world folder.

Hm. I honestly do not see the issue. What I thought would be it isn't it.

Any idea what line prints it? I can try debugging it but I don't even know what prints it. 

So far all I've been able to find is that ClientboundLevelChunkPacket is settings biomes to a full -1 array in the constructor, which is then causing the message client side. I traced that to ChunkGenerator.createBiomes(), where the registry does not have a plains biome which is the fixed biome, but I also checked the vanilla chunk generator and it also doesn't have a plains biome, so I'm not sure whats wrong.

Okay my guess is that the problem is that you are using the plain biome instances from the normal registry in your RealityCubesSettings, specifically Biomes.PLAINS. You have to use the dynamic registries to look up the actual biome for the world, otherwise the IDs won't be correct, afaik.

I think that is the problem. I changed to using ResourceKeys instead and haven't seen the log since.
