Hi,
In the room where a girl is hold hostage by Yanos I used a Silence cleric spell level 2 but then, the enemies could move and be free to cast their spells. The game tool tip wrote "silenced" on all enemy npcs.
Is silence a area spell which dispell when you leave the area?? In no other game does it work like that so I find that really strange.
Edit apparently it works like a area spell... that's really not what the spell describe.
(Sorry for no further report, I'm going back to pathfinder kingmaker until next version which remove the CTD's.)
