Help: IsCasting SpellHas

[solsticeaurora]

Hello.

I am trying to add conditions to an ability but for some reason, the game crashes every time.

The ability itself (Weakness) works as it should, but these conditions cause a crash every time:

Subject IsCasting
Subject MagicSpellHasKeyword

Subject IsCasting
Subject SpellHasSkill

Subject IsCasting
Subject SpellHasCastingPerk

There are also crashes when I use other conditions that include or exclude skills like Destruction or Illusion etc.
I have tried using Target for the spell condition, but that does not work either.
