Error on Server when Mungus explodes

I'm having trouble with the mungus in the modpack that I created/maintain (CrewTowns). Whenever they explode, there is a server side error, and the biome does not change. This happens with the default type (red mushroom -> mushroom fields), and the types I added (cobweb -> ominous woods)

Here is the config:

#0 = no mungus biome transformation. 1 = mungus changes blocks, but not chunk's biome. 2 = mungus transforms blocks and biome of chunk.
    #Range: 0 ~ 2
    mungusBiomeTransformationType = 2
    #List of all mungus mushrooms, biome transformations and surface blocks. Each is seperated by a |. Add an entry with a block registry name, biome registry name, and block registry name(for the ground).
    mungusBiomeMatches = ["minecraft:poppy|minecraft:plains|minecraft:grass_block", "minecraft:dead_bush|minecraft:desert|minecraft:sand", "minecraft:cobweb|biomesoplenty:ominous_woods|minecraft:grass_block", "minecraft:red_mushroom|minecraft:mushroom_fields|minecraft:mycelium", "minecraft:brown_mushroom|minecraft:mushroom_fields|minecraft:mycelium", "minecraft:crimson_fungus|minecraft:crimson_forest|minecraft:crimson_nylium", "minecraft:warped_fungus|minecraft:warped_forest|minecraft:warped_nylium"]

The error seems to be a forge registry look up issue

java.lang.NullPointerException: Cannot invoke "net.minecraft.resources.ResourceLocation.toString()" because the return value of "net.minecraftforge.registries.IForgeRegistry.getKey(Object)" is null

Looking into the code at this section in EntityMungus.java:

int id = this.getId();
setChunkBiomes(chunk, container);
AlexsMobs.sendMSGToAll(new MessageMungusBiomeChange(this.getId(), pos.getX(), pos.getZ(), ForgeRegistries.BIOMES.getKey(biome.value()).toString()));

The call to ForgeRegistries.BIOMES.getKey is returning a null, so I'm assuming there is something wrong with biome.value().
From what i can tell, the biome object is looked up by the mushroom type, and when it is not found, it returns null.

I searched the logs for possible errors and verified the biome IDs, but I cannot find anything else wrong.

Please help.
