I have to correct myself on some things i wrote above.

The edible items only display the wrong AP cost, in the Ap bar, where too much APs turn red - but when you use any of them they all actually cost 3 APs. As they should, according to their descriptions.

correction on the previous spoilery "problem":

Evelyn does summon her support earlier. In previous version it was about half her health... but now she doesnt wait that long at all. Which is good. Great. telepathy?

But, i did fight her now and managed to get her to very low health, about 10-15% (maybe 20%), while she was frozen and then stunned all that time. I tried just clicking turns and not attacking her anymore after that, to see if she would call reinforcements but, she didnt no matter how long i waited. She just casts some ordinary spells at my characters and nothing else, for many turns.

So... maybe the "problem" is reversed now? :P

I tried that only once, though. After that i tried again, avoiding to get her stunned or frozen and she called her goons very soon, almost at the very start.
