Why: When you override a parent function (like BeginPlay or Tick), the parent's logic usually still needs to run. Forgetting to call Parent: <FunctionName> can break initialization.

Fix: In your overridden function, right-click in empty space → search for 'Parent: <FunctionName>' (e.g. Parent: BeginPlay). Add that node. Wire it to the exec input early in your function, before your custom logic.
