Good morning everyone! I have a question about affinity between wolves in a pack. (Sorry for the long post...)

One of my pups, Sign the Dotted Line, has a Strong Like affinity with all the other wolves in my pack except one; with the one exception, he has a Like affinity. Otherwise, he strongly likes the other members of the pack. However, in his info (right under his name where it says "Affinity With Your Pack"), it says he just has a "Good" affinity with the rest of the pack. Whenever any of my other wolves had the same relationships within the pack as he does, they would be marked as having an Excellent affinity with the rest of the pack.

Here's my question... Does anyone have any idea why he would be marked as Good instead of Excellent? Could it be a bug or possibly that the "Like" affinity with the one wolf is so close to being a Neutral relationship that it makes that big of a difference? Or could it be something else entirely?
