I'm having trouble getting Ocelots to stop spawning in Jungle biomes. Here's the script I've been testing with:

jungle = forBiomes(21)

jungle.set("isSpawnBiome", true)
jungle.removeFeature("ANIMALS")
jungle.removeAllSpawns("CREATURE")
jungle.removeDecoration("TREE")
jungle.removeSpawn("net.minecraft.entity.passive.EntityOcelot", "CREATURE")

allButJungle = forAllBiomesExcept(21)
allButJungle.registerGenBiomeRep(21)

I added the removeSpawn() call after I found the other script commands weren't removing Ocelots but it didn't help. The above is just a test script to reproduce the problem - I noticed them in jungle biomes using another script that doesn't limit to just jungle biomes, so it looks like a general problem.

Here's some version info:

Minecraft 1.12.2
forge-1.12.2-14.23.1.2600.jar
BiomeTweaker-1.12.2-3.1.312.jar

I also tried with the latest build on jenkins but the same thing happens.

Here's the output script for the jungle biome in my test world:

You can see the net.minecraft.entity.passive.EntityOcelot entry is still there but all other animals are gone.

Thanks for keeping up all your hard work on this great mod. I was very happy to see the 1.12.2 version!

Yup, that worked perfectly. Thanks!

Ocelots are classified as monsters in the spawn lists. You can see them registered under "MONSTER". Change the line

jungle.removeSpawn("net.minecraft.entity.passive.EntityOcelot", "CREATURE")

to

jungle.removeSpawn("net.minecraft.entity.passive.EntityOcelot", "MONSTER")
