Think this is a glitch, and also at times deliberate. It happens aloooot if you have the Bitchy Wench in your party aka Le'azel Shadowheart hates her as she often rags on you for having BW even in your camp. It gets worse if your actually using BW.
Bug/glitch = she vanishes even if she's in your party and can usually be found (I've noticed) in your camp. Think this part is a bug/glitch but unsure.
For the most part you'll find her somewhere in the world, and you can readd her if certain conditions are met. This has earned her the nickname of Fickle Cleric.
yes I have a nickname for all the members I recruit. Cause sometimes their name eludes me.
