When doing the Rituals in Fixed Camera Mode, when a Storm Of Souls disturbance happens north of the pedestal, it is very difficult to click through the three phases. It keeps wanting to go to placing the light source as opposed to the disturbance.
Using "Battleship" lingo, I suggest moving the light sources from A5 and B5 to A4 and A6.
One way to fix it is to manually click to move to the left or right of the affected glyph while you wait for the next phase.
Because you usually end up standing on the light source plot when moving to the glyph by default, the game gets a bit confused regarding the hitbox.
It's nice to be important, but it's more important to be nice.
