I created a Blueprint Interface called BPI_AddScore and I would like to implement the interface in BP_PlayerController. However, the Implemented Interfaces menu does not have the Add dropdown menu.
Evidently this is a known interface bug with UE 5.1.
Naming for Inherited Interfaces and Implemented Interfaces is reversed in 5.1 and Main. Inherited interfaces act like implemented interfaces, and inherited interfaces appear listed under Implemented interfaces.
