- Cleaned up the apparent mess that is pc_skill. Hopefully it SHOULD fix as described on the docs now, this should also fix adopting not correctly giving the family-related skills. The flag value of skill should be: 0 to set the skill (if skill level is 0, this removes a learned skill), 1 grants the skill as an item bonus which is temporary, and 2 will add a skill bonus like 1, except the skill level adds up to whatever level already known of that skill.
