Attempting to change a spotlight in a child component referenced by a parent blueprint from movable to stationary and then running PIE crashes editor

Changing the mobility of a light component within a child component that of a parent blueprint and then entering PIE without compiling crashes the editor.

Frequency: 3/3

Crashreporter: N/A

Regression (Yes) issue (does not) occur in 4.10.4

1. Download, unzip, open attached project
2. Open Child blueprint
3. Select Spotlight component
4. Set Mobility to stationary instead of movable. Do not compile the blueprint
5. In the editor, place a copy of the parent blueprint into the level viewport
6. Press PIE

Results

Editor crashes

Expected

Viewport is set in PIE, player can move in level, parent blueprint appears in level.
