Unfortunetly there is still no fix for the Almira bug in act 3 (
http://larian.com/forums/ubbthreads.php?ubb=showflat&Number=636583&#Post636583).
She is still gone, although she joined you on the ship in act 2. The bug occurs when you put the tablet (which you shouldn't even have anymore!) into your chest on the lady vengeance before you start act 3.
Hopefully you guys adress this in the next patch.
