Ice Nova + Astral projection + Spell Echo world space spawn offset

Hi,

Since 0.1.1c, the use of Ice Nova + Astral Projection + Spell Echo causes an offset of the nova's world position.
There "often" is a random offset when converting mouse screenSpace postion -> nova worlSpace position. The more enemies on screen, the more it happens (it seems).
It does not happen when alone on screen.

I say random because I can mouse click if front of the character and the nova spawns behind, or on the sides.

Also, sometimes, the Echo of the nova is not where the first nova hit.

Before 0.1.1c, the behavior of the spell, with this combo of support gems, was okay.

To be clear, I'm not talking about the ofsset created by clicking on the environment where the Nova can't spawn. It happens when clicking on enemies or space where it should spawn.
