Freezing Tulgraft is bugged: it does not fire projectiles to chilled enemies as it should

Freezing Tulgraft
While equipped, this Graft will periodically fire fling icy mortars (falling crystals) at Enemies in range that are Chilled or Frozen.


Falling Crystals
Fires mortars at up to 4 additional Chilled or Frozen targets in range


It does NOT work, how to reproduce
1- Equip a Freezing Tulgraft
2- Equip and turn on "artic armour"
3- Walk, artic armour will generate chilled ground
4- Enemies in chilled ground are chilled but Falling Crystal are not fired to them

Yes, it seemingly does not work against enemies that are chilled by chilled grounds.

Another way to replicate the bug is to use frostblink: Normally frostblink itself chills with cold damage, and also leaves chilled grounds. If you support frostblink with void manipulation to eliminate the cold damage and only leaves chilled ground, enemies will still be chilled but falling crystals will not fire.
