Please still attach a full log, but the next Beta will have some updates for Despair:
* Actor.HasCurseFrom updated for 'Despair'.
* Actor.IsCursingWith updated for 'Despair'.
* Actor.IsCursedWithDespair and Actor.IsCursingWithDespair added.
Release has the updated API for Despair and the next Beta that will be deployed in a few hours will too, so that should hopefully fix your issue for the custom CR you're using.
