1. Launch: UE4Editor.exe (any project)
2. Select a static mesh in the Content Browser
3. Right-click > Asset Actions > Create Blueprint Using This...
4. Select another static mesh in the Content Browser
5. Right-click > Asset Actions > Create Blueprint Using This...
6. In the new blueprint, open the Graph
7. Right-click in the Event Graph
Result:
Crash. Note that this only occurs on the second blueprint created from a Static Mesh, and only if done so using Create Blueprint Using This. This also occurs when creating a blueprint with this method after creating BPs from static meshes through the Details panel, but does not occur when simply creating a BP using the Create... button.
