Animate Weapon bug w/ Sidhebreath, Paua Amulet

Level 4 character.

Equip Ethereal Knives, equip Animate Weapon.
Both unlinked to any supports, no minion dmg related nodes in tree...

Cast EK, cast some AW, aw minions do some good damage...
Equip Sidhebreath, cast ek, cast aw, expect CRAZY low level base damage..

Unfortunately, the interaction between Sidhebreath and Animate Weapon is broken.
The lingering blade minions do not gain the base additional cold damage.
The lingering blade minions DO inherit the 50% dmg converted the cold, and deal no non-cold damage.

The result is that the AW minions now do half damage..
I went from glass shank base dmg + aw skill added dmg (100% phys)
to glass shank base dmg + aw skill added dmg (50% cold) with no bonus additional cold damage from Sidhebreathe.
