Lycanthropes gain animal levels and can be human (Which is granting an extra skill point per level), the natural fix is to use 'BONUS:SKILLPOOL|CLASS=Animal;LEVEL=1|-1|PRERACE:1,Human' however, this doesn't fix problem.
We need to allow Skill Points gained to drop to 1.
Sorry, BONUS is still a wee bit on the low intelligence side of things. Proper syntax requires a dot. Thus, it is:
BONUS:SKILLPOOL|CLASS.Animal;LEVEL.1|-1|PRERACE:1,Human
Can you try that and report if that does not work?
The Period did the trick. Thanks Tom!
