DO NOT FORGET !! Items disappear from character's inventory if dismissed to Stronghold. You need to empty the character's inventory (NOT the equipped items, just the inventory) before dismissing them to Stronghold to avoid the unpleasant surprise. I found this bug when I replaced Aodh with Grieving Mother, leaving on Aodth all my grimoires found. I noticed that I remained without them when I recruited Aodh back. FUUUU !!!
