Kingdom titles and favor cost

[feldoh 74]

The cost for spells with titles should be half favor, this works. But when trying to cast a 20 favor spell, while having 15 favor it tells me my favor is too low. So i still need to wait for 20 favor to cast only to spend 10- So the check for casting still checks orginal cost not actual favor i need to cast.

Some spells have a minimum favor required on the caster unrelated to what you actually use, same goes for linking.
