Factorization: Disabling Colossus from showing up?

[Benie76]

I'm using the direwolf20 pack(v1.2.1). Looking for a new base, I found a really nice one. Yet it's near one of these weird bunny-like Colossus things that the treasure map leads you to.

Is there a way I can remove these without having to create a new world? I really want to have my base near here, but this thing just.. it fits out of place.
I do know these things can be "killed" by destroying the eye. Did it once, but its corpse just sat there. Was unclickable. Which is why I want them removed.

Well, if it gets stuck you can use mcedit to remove the entity. Be careful not to reload the chunk it is in too much while fighting one, it glitches out way bad.
