yes, exactly as in the attached archive. One pack for all three, not modified by me. For example, this doesn't happen with Ents; everything is in order there. Maybe I'll figure it out later.

Crashes of the Dark Knight are more likely not due to skills, but due to animation (possibly due to slowed-down approach animation).
But there is a similar case for skills; the creature Maenad (a kind of shaman) has fear and regular poison, and it can also crash when controlled by the AI.

But there is a suspicious thing here (not only here, but in 4 places in the folder below. I fixed it and am testing now, but it still crashes):

2) attack00.(BasicSkelAnim).xdb
