Since GetThenPin was added to UK2Node in 5.x, derived classes don't need to provide their own implementations. These were largely identical to the one in UK2Node. Additionally, overriding non-virtual functions can be error prone if there's an expectation of polymorphic behavior. #rb dan.oconnor, jodon.karlik #rnx [FYI] George.Rolfe [CL 35782464 by dave jones2 in ue5-main branch]
