So I was recording my Alien challenge tonight and I had alien abduction chance at 1. My understanding is that should mean 1% so did I actually have. Natural abduction or is my thinking off?

Do you mean kAbductionBaseChance under AlienUtils? A setting of 1 should be 100%. If you want 1% you'll need to set it as 0.01.

Okay, that's kind of what I thought might have happened after I noticed it. Booooo. I was kind of excited about a 'natural' abduction. Oh well.
