AddDebugItem LNK2019 for FNodeDebugData

Hello,

I have extended runtime class FAnimNode_SkeletalControlBase class and in FAnimNode_Base interface method “GatherDebugData(FNodeDebugData& DebugData)” accessing “AddDebugItem” method causes linker error. Someone else also had similar problem ( link below ). Can someone explain why it is not resolving symbol for only that one method when other methods in the struct (FNodeDebugData) such as GetNodeName work fine.

Thank you.
