Can't take control of Qara and Zhjaeve after reading the ancient book

[Alierna]

I've just finish the Ammon Jerro’s Haven when I see that after reading some sentence of the ancient book

(http://www.gamebanshee.com/neverwint...erroshaven.php)(#8)

at random I can't take controle of my two last character who is Qara and Zhjaeve they continue to help me and follow me but I can't do anything with they (leveling up, inventory, cast, special ability) cause I can't take control of they.

I think I spoke two time the spell of dominate who is in the ancient book but same after trying several time to change my party, rest or just take one of them with me there nothing happening and I can't take control of they.

Wish someone has an answer for me

Thanks
