Compiling a Blueprint that uses a Select node with two different variations of Actor will crash the Editor in 4.9

Compiling a Blueprint that uses a Select node with two different variations of Actor will crash the Editor in 4.9. In 4.8.2 binary, one input of a Select node will be disconnected on restarting the project if the two inputs are from different classes. For example, Actor and a child of Actor as Select inputs. Image attached for clarity.

Reproduced in 4.8.2 binary and Main (//depot/UE4/Promotable-CL-2623997). This is a regression; neither the pin disconnect nor the crash occurred in 4.7.6.

1. Create a new project
2. Create a new Actor Blueprint
3. Create the following setup in the Event Graph:
[Image Removed]
4. Compile (Note: In 4.9, the editor will crash here)
5. Close and reopen the project

Result:
In Main, the editor crashes on compile. In 4.8.2, one of the Select inputs will be disconnected.
