Sad sad... I loaded different save (I am searching in my database for most strong hereos who may buy as much changeable units as possible)... but this time I didn't get my book of death... bug? (to change my units into army of dead units - I have alchemists in my army right now)
after ALT + TAB it works

funny.
But from other bucket:
When autocombat is selected - the AI can't really handle the new skills (even as I thought they should work in the same way... most of them )
AI moves my AoD units as if they would not have skills - still I know that AI used the alchemyst and dryad skills pretty well (before the poor creatures were Necromancizied)
