Ardent Censer's healing isn't being tracked post-game
I think, anyway. Last game I had upward of 7000 healing on Ardent Censer and 2000 on Stoneborn Pact, but post-game only showed 2800. I would assume at least 800 from Relic Shield, so it appears all of Ardent Censer's healing just isn't being tracked.
Splitting Healing Done into Self Healing and Outgoing Healing/Shielding would really help catch these bugs, too. (Self-Shielding is presumably already covered in self-mitigation).
