Crash when splitting up output of collapsed node

So I was working on this Blueprint here:

When I now delete the Location connection, right click the Location node of the collapsed PositionAtCursor (which only calculates a HitLocation of the Cursor using GetHitResultUnderCursorByChannel) and try to compile after that, UE4 crashes.

This is easily reproducable:

  • In a Blueprint, create a “MakeVector” node.
  • From the Return Value, create a “VectorLength” node.
  • Right click the “MakeVector” node and click “Collapse Nodes”.
  • Alt+Click the connection to delete it.
  • Right click the Return Value of the collapsed node and click “Split Structure Pin”.
  • Compile.

This should instantly crash the engine.
I don’t know if this has been posted before, but I hope I was able to help with this.
