As the title said : I have a palladin - oath of the crown - in my party. ( respecced Lae'zel). And when Shadowheart releases the Nightsong from her cage, Lae'zel's oath is broken.
I don't understand the reason.
Note that in previous PT's I had Minthara with me, an oath of vengeance palladin, but she never had a problem after releasing Nightsong.

Any ideas on this ?
