To Whom it May Concern (my apologies if this is a known issue):
It seems that the Spinner of Shadows has some bugs post u51 and the first post-u51 patch.
Went in on Epic Elite directly from Servants of the Overlord and the Spinner was impossible to damage, even standing in the silver flame. She apparently isn't taking stacks of the debuff from the silver flame spirit.
So after 5 minutes or so of thinking it was just me, I recalled.
I went in the front door this time (directly from the Harbor) and this time not only could she not be damaged, but the spiders failed to spawn entirely.
So I am thinking maybe there's an issue on the back end that needs to be addressed.
Cheers,
Suly
