MobHunting v6.0.7
Error log: https://pastebin.com/raw/yKZUrLTg

This happens because you have entered a "chance" wrongly for one of your mobs in the config.yml

Can you help me to find where is it?

Or maybe it is because you have disabled by removing the command

cmd:

if you dont want a command you should enter

cmd: ''

but when you set the chance to 0 you dont need to remove the default command...

After adding '' after cmd: and removing '' around chances all became ok.
