Incinerate does not trigger Raging Spirits

"While active, your fire spells will also summon Raging Spirit.....". This not happens if Incinerate is being used for Witch

I can second this problem.

A bit more info to fix it:

Raging spirits are triggered when Incinerate is placed on any other button than left click. It does not trigger when used on left click (which is what I used it on for a long time).

I also tested if it works on controller and there's no problem when it's on the R1 button for example. Can't put it on X (interact button), so maybe that's the root of the issue on mouse controls?

I strongly suggest that GGG looks into this as it is something that makes a character significantly weaker while at the same time is very easy to miss in the heat of the battle.
