Summon Dark Effigy spawns in random spots ignoring the mouse cursor

Bug report reference number: 2,928,485,188

Upon casting, Summon Dark Effigy from Soul Splitting Warlock Ascendancy node totally ignores the mouse cursor location and spawns in a random spot around the character. Toggling the "Always Attack Without Moving" doesn't change this behaviour. The character also doesn't move to face the location of the cursor upon casting so it seems it's like a non-targetable ability right now.

Having no agency over where the effigy spawns makes the ascendancy node extremely clunky and dangerous to use.

Steps to re-create the bug:
1) acquire the Summon Dark Effigy skill
2) cast it anywhere, no matter the small obstacles in the area
3) observe the location of the spawned effigy being unrelated to where the mouse cursor is when you cast it
