Kangaroo Area Component behaving very differently for two very similar curves

Hi everyone,

I was trying to use Kangaroo's new area goal to reduce the area of a closed curve by a given factor. I'm actually using one of the example files that Daniel posted, the script seems to work fine for some curves but not for all. 

Attached I included the GH file with two very similar input curves, one works perfectly the other is totally wrong.

any ideas?
