Worldgen graph tab disappears when I use the generated world-gen.json

[GoldMikeMan]

On Fabric 1.20.1

It works fine normally but when I use the scanner and put the file in the config folder the tab just disappears completely. Hoping you could shine some light on why if it's a user error problem but figured I should put it here in case it's something that needs fixing.

Attached is the log and the world-gen.json.

Hmm, interesting, never seen this error before. It seems that JER crashes here. Specifically, it might be related to BetterNether messing with biomes?

(Why does this happen even though your world-gen.json mentions nothing about nether? I think because when there's no world-gen.json, readDIYData isn't called at all.)

So I think this is a JER problem. Searching in JER issues, there is already an issue for it, way2muchnoise/JustEnoughResources#469 .
