The Component Details tab stops working after setting a Blueprint-owned ChildActorComponent class to AbstractNavData and then reloading the Blueprint asset.

Choosing 'AbstractNavData' as the class for a ChildActorComponent inside a Blueprint class and then relaunching the editor seems to break component details panel editing the next time the Blueprint editor is opened and the ChildActor component is selected.

Did not seem to occur for other CAC class types. Discovered this while working on [Link Removed].

1. Launch QAGame editor.
2. Create a new Actor-based Blueprint class.
3. Open the Blueprint class in the Blueprint editor and add a ChildActor component.
4. Select the ChildActor component and set the ChildActorClass to AbstractNavData.
5. Compile, save and close the editor.
6. Relaunch the QAGame editor and reopen the Blueprint class.
7. Select the ChildActor component and attempt to set the ChildActorClass. Note that in the Details tab, the drop-down does not expand to show available class types, hovering over other widgets doesn't initiate a highlight effect, and generally the ChildActor details editing seems to no longer work. However the rest of the Blueprint editor seems to function OK.
