[Patch 6] Light cleric with radiating orb item

Hello

I think since patch 6, the radiating orb items behave differently.

I have the following items equiped on my cleric:

• Luminous gloves : Apply 2 orb each time I deal radiant damage.

• Corruscation ring : Apply 2 orb each time I deal spell damage while illuminated by a light source.

• Blood of lathander : Just to make sure i'm illuminated.

The spirit guardian spell only apply 2 instances of radiating orb. Before patch 6, i'm nearly sure it was applying 4 instance with my build. Same thing with radiance of the dawn.

However, sacred flames is able to apply 4 instance of radiating orb with a single cast.

Is it a known bug since patch 6? I didn't find anything about this problem.
