This is a weird bug. Try to do the following:
1. Create a new Sov
2. Edit his stats to 15/15/15/10/10/10 or something similar - only 1 thing is important: only 5 "design" points should be left
3. Go to the talents tab
4. Choose Ugly & Outcast -> 11 points left -> Cannot choose Naturalist or Tracker [Both of these are 10p talents]
5. Choose Ugly & Cruel -> 11 points left -> Cannot choose Tracker, but Naturalist is available now
There are more stuff like this, but this weirdness is probably related to one bug.
