Uber Graph Persistent Frame - All local variables, used by event graphs (see FKismetFunctionContext::EventGraphLocals), are no longer stored in class scope. They are stored on a frame (as local variables in regular functions). For the ExecuteUbergraph_*() functions the FFrameÆs allocation is kept for the life of the object.
