Hey ,
I have tracked down the issue you are having. In your “BP_Ability_Actor_NAME_#” classes there are some invalid replicated properties trying to be used, which is why you see the Assert error. This is the engines way of telling you that something you are doing is incorrect.
The four variables I believe are the issue:
- TargetLocation
- TargetActor
- TargetingRequirements
- TargetingBehaviours
