What happened?

Running a very simple set of mods to try and deduce what the issue is here.

• BiomesOPlenty-1.16.5-13.1.0.485-universal
• byg-1.3.5
• jei-1.16.5-7.7.1.152

Both times ran with the default world type. BYG config set to allow byg to control the nether and end biomes, confirmed in the level.dat here: level_dat_with_and_without_bop.zip

crash-log

Crash without BOP: crash-2022-03-27_00.32.58-server

I found the problem and now I feel dumb! At some point I must've been testing with BOP installed, because there were BOP biomes in the config, so it was still trying to generate those biomes that no longer existed >_<

make sure you remove entries with a weight of 0 in your config, i need to fix this, i'd suggest VScode to validate/verify your json syntax: https://code.visualstudio.com/

I didn't see anything with a tag of "weight": 0 but if I had an entry that didn't have a weight tag I should add one? Like I found this one;

"byg:canyons": {
  "hills": [],
  "edge": "byg:canyon_edge",
  "beach": "byg:canyon_edge",
  "river": "byg:canyons",
  "climate": "WARM",
  "dictionary": [
    "OVERWORLD",
    "MOUNTAIN",
    "PLATEAU"
  ]
