When trying to put a baby goat in a cage from supplementaries, the game crashed.
Maybe this is linked with the model you did for the goat ? I couldn't join my world until I uninstalled cold sweat.
Forge : 40.1.86
Cold Sweat : 2.2 b01c
Supplementaries : 1.5.14

For the moment, I'll just edit the config from supplementaries and remove the fact that you can put a baby goat in a cage.
