Ball Lightning of Static does not work properly with Traps/Mines

I had an idea to cast ball lightning of static (transfigured version of ball lightning) with traps and sadly it casts into a random area when a monster steps close into the thrown trap. I have also tried it with mines and it does the same thing. I thought it was because of the Triggerbots, but it wasn't.

Please GGG look into this. Thank you!
