I know its not possible using the CS to remove unwanted creature additions in creature mods. But is it possible to simply raise the level in which they appear? (using CS) to something so high I wouldnt see them anyway? Im looking at you frostracer from BOV!

It is possible to remove creature additions, and it's also possible to raise the level in which a certain creature appear.

What you are looking for to do that will be in the leveled creature tab in the CS. You will have to hunt a bit for either a new entry there or a changed entry in the normal lists, which should show marked as changed.

Thanks, how do I go about deleting them? Can I just go to leveled creature tab, right click unwanted creature and select delete? If not that then how can I raise the level in which they appear? What would clicking 'blocked' do?
