So I have NuclearCraft on a server I'm running and playing on and the Paul/Brians are fine, other than the annoying sounds they make. I've disabled them both in the config and restarted the server yet they still appear. I even tried disabling all mobs from the mod and they still spawn. Is this a glitch or are they just impossible to get rid of? I'm running 1.7.10 with mod version 1.9f

Hey there - the disabling of their spawning should work fine, but it will not remove any of them which have already spawned. You should be able to kill all types of a given entity using the kill command.

Just put out a new 1.7.10 build which will kill any Brian and Pauls in the world if they are disabled :)

How can I remove Paul and Brian?

@Sumis34 There is a config to delete them in the last 1.7.10 build.
