Game Mechanics: Spells not finishing.

[Kazi]

Can confirm as well. Has happened multiple times and am fairly positive it costs mana. Might have something to do z axis? Are mobs dipping into a gully when the spell goes off?

I've been taking screenshots everytime I cast a spell to see if i can get a before and after.

If they are between hills I always get the cannot see target fail message, I only get the no message no cast when i should have had los or i believe i should have.
