Bug (Maybe?): Irovetti Unaffected by Feeblemind

[Karkesis]

In the fight with Irovetti, I hit him with a Feeblemind (failed saving throw) and he was still able to cast spells afterward. I'm not sure if this is intended or not. On the one hand, it's a direct contradiction of the function of the spell. On the other hand, that's a really easy way to cheese a boss fight.

Feeblemind currently only causes the next attempted spell to fail once, at least from my observations.

Thought I had shut down a summoner, only to be swarmed with their summons two turns later.

EDIT: added "their" for clarification.

That's vastly different from my experience; up until now every time I'd used it, it completely stopped the affected enemy from casting altogether. Made the fight with the two gnomes and their golden golems in the palace an absolute breeze.
