spark doesn't hit tormented mutilator animated weapons

as above. When a tormented mutilator spawns animated weapons, they can;t be damaged by spark at all.
it's caused me to die several times now, as the animated weapons aren't visible when in a big fight, and without taking any damage, their health bars don't show up.
arc hits them, orb of storms hits then, my golem hits them, but self casting spark or having spark totems doesn't hit them. doesn;t matter if it's voltaxic spark or normal lightning spark

Spark is a ground projectile and animated weapons are flying monsters. Annoying, but intended.

that's different behaviour from most every other projectile I've used. the game doesn't seem to care about the verticality of projectiles when they cross the same space a monster is in. the parasitic birds from act 4 get hit by the spark projectiles even when they're doing their flying charge attack.

Something's still wrong if one specific mob doesn't ever get hit by one specific spell.
that shit leaves me wide open and vulnerable on any spark characters.

It's not one specific anything. Spark, Arctic Breath, and Lightning Strike all use ground projectiles. Animated weapons and Raging Spirits are classified as flying creatures. That's of the top of my head. I think there are more. And likely will be more in th future. Did you notice spark bounces off all the low objects? Non ground projectiles fly over the small obstacles. Working as intended.
