 * Once you have disintegrated something or someone and you leave the area you are in, by entering another area or fast traveling away, upon your return you will be awarded again for the goo/ash piles left in that area. For example, if you create 4 goo piles and you leave the area with a challenge score of 4/32, when you come back to this area again, your score will increase to 8/32.
