Description
REGRESSION: Yes, does not occur in 4.17.2
Ensure occurs when undoing the splitting of a pin.
Steps to Reproduce
Open QAGame in editor.
Open the level blueprint.
Create a vector variable
Drag the variable into the level as a Get node.
Right-click the pin and select Split Struct Pin.
Undo.
RESULT
Ensure
Callstack
Ensure condition failed: Node->GetOuter() == GraphObj [File:D:\Framework\Engine\Source\Editor\GraphEditor\Private\SGraphPanel.cpp] [Line: 1417]
Found K2Node_CallFunction_429 ('K2Node_CallFunction') that does not belong to EventGraph. Node Outer: ExecuteUbergraph_QAClickHud, Node Outer Type: EdGraph, Graph Outer: QAClickHud, Graph Outer Type: Blueprint
