Actor Component instances have their settings reset to default when compiled in 4.17 (Compilation Manager)

REGRESSION: Yes, does not occur in 4.16

When converting a 4.16 project to 4.17, any actor component instances will have their settings reverted back to default when the user compiles the blueprint.

Does not occur with Compilation Manager off.

1. Download and extract the attached project.
2. Open it in the 4.17 version of the editor (can use Create a Copy method if you want to preserve the 4.16 version).
3. Open TestMap.
4. Select the BP_ACtor instance in the level.
5. In the Component Editor, select BP_ActorComp. Notice that Default On is false.
6. Open BP_ActorComp in the blueprint editor.
7. Compile it.

RESULT

In the instance, Default On is set back to true.
