Inevitable Agony Bugs With Doedre's Undoing and Decaying Hex/Contagion

Inevitable Agony currently has a bugged interaction with Doedre's Undoing Lineage support. It will proc the damaging component of the support, but it will not apply the curse. It seemingly doesn't even attempt to apply the curse as you can apply a different curse (e.g. despair) with a curse limit of 1 and it will not attempt to overwrite the curse, leaving the first curse intact for its normal full duration.

Additionally, Inevitable Agony does not interact with decaying hex to propagate off of Contagion when an enemy dies.

I second the Doedre's Undoing. Does not apply the curse at all
