Bug FTB Departed Assassin excess spawning; need mass kill method

[Inferius77]

The title says it all: My friends and i are playing FTB Departed. After about 30 hours or so the number of entity.nevermine.Assassin.name all around our base is ridiculously huge. Without CoFH commands i have no clue what to do. i just installed forge essentials but found out the butcher command wont kill the passive assassins. I'm been wasting hours of my night searching everywhere for a way to kill them all but im going insane. at this point id be satisfied for a way to just wipe all currently spawned mobs. Anything, please.
i typed this up quick , sorry if not professional.

I believe a new non-recommended version of Departed hit the launcher yesterday, if that has the newest AoA in it (I believe it does) the assassin issue has been fixed. If the new AoA is not in it, you can download it seperately and update the version in the pack.

You will want to go to server.properties and set the game spawning to disabled (both monsters and animals) then set to peaceful. Start up server again and log in just to be sure. Then update that mod as the above poster said to prevent it from happening again then restart the server on your original settings.
