Lightning Warp doesn't trigger

There are clearly multiple highlighted enemies that can be culled, however the character simply does the casting motion without actually warping into the enemy... This is very frustrating, especially when I'm low on life and need a getaway/life steal.

My guess is the Spark spell somehow conflicts with it, but it's up to the dev to confirm.

I bind the spell to secondary skill set but I don't think that matters - the input is being correctly recognized.

I also made sure that I have enough mana. And yes the enemies are just within a meter even I wasn't aware of any distance restrictions of this spell.
