Fobidden Arcana - focused Spellcaster

[Just Pete]

Am I missing something? Using karma gen mode.

Focused spellcaster gives free spells = current spellcasting ability +1 for specialization, and spells cost 4 Karma instead of 5

When I add it to my caster, all I see is each spell costing 4 karma - no free spells.

Likewise even before forbidden arcana was released, and continuing now, the adjustment for adding free spells doesn't appear to do anything.

Is this a bug, or am I missing something?
