What you were expecting to happen, and what actually happened:
Expecting to gain “Souls to Shrine of Treachery” 14 + 26 , like the “Delve Gold” is added to Shrine of Cunning. How often does this happen? When did it begin happening?
Since 6.1 update
Steps to make it happen again
Play a delve battle and earn delve room souls.
This is probably “working as intended”. Only “basic” souls are considered “correct”.
I have the same issue with the campaign tasks “Get xxx glory”. You can only get the “correct” glory from rPVP & cPVP. Nothing else counts.
