Removed component used in 'Get' results in load warning but not compile warning

Our cooks recently started generating a warning like this in two blueprints -

LogBlueprint:Warning: [HandEntry] 'Affordable' variable not found. Base class was probably changed.

Opening the Blueprint shows no errors and it compiles without warnings, but browsing/searching for the node shows the culprit -

[Link Removed]

It would be nice if these were consistent (and I'd vote for the former not being a warning if the node has no connections)

Create a blueprint and add a public boolean variable to it.
Create a child blueprint and place a get of the boolean on the graph.
Compile and save both blueprints.
Delete the variable, compile and save the parent.
Use the reload asset action on the child blueprint.
Note the warning in the log.
