Blueprint fails to compile when broken struct pin of Get Class Defaults is used

When the Get Class Defaults node contains a struct pin, breaking the struct causes the resulting pin to read "StructName_StructVarName". This causes the blueprint to fail to compile if the pin is used in the blueprint.

1. Open UE4 Editor (any project)
2. In content browser, Right Click->Blueprints->Structure (TestStruct)
3. Create and open blueprint based on actor (TestBP)
4. Add variable to TestBP and set type to TestStruct
5. Right click to add Get Class Defaults node
6. Right click TestStruct pin and select Split Struct Pin
   • Note pin now reads "TestStruct Member Var 0"
7. Wire Begin Play node into Branch node
8. Wire TestStruct Member Var 0 pin into Branch Condition
9. Compile BP

Result:
BP fails to compile because it is looking for "TestStruct Member Var 0" variable that doesn't exist

Expected:
Blueprint recognizes pin is part of the struct variable rather than a variable of the blueprint itself

Splitting a struct pin on a Get Class Defaults node causes problems
