Actual Behavior

For some reason, even after editing both the server and the client config files for Animania to allow vanilla animals (i.e. B:replaceVanillaCows=false), the following animals still won't spawn in game from spawn eggs, or naturally in the wild:

Sheep
Chickens
Cows

Pigs and horses seem to spawn fine from vanilla eggs, and they appear in the wild.

Minecraft 1.12.2
Animania 1.12.2-1.4.8
Multiplayer server.

Hmm... you might have an old config, with old entries.

On 1.12, it should be:

B:"Remove vanilla Chickens"=false
B:"Remove vanilla Cows"=false
B:"Remove vanilla Horses"=false
B:"Remove vanilla Pigs"=false
B:"Remove vanilla Rabbits"=false
B:"Remove vanilla Sheep"=false

Basically, I just tested and it works fine. You can also/check use the in-game Config editor to be sure.

Couple of other notes,

• Vanilla eggs don't work if these are set to true
• Re-spawns of vanilla animals are very slow after the chunk has been generated
