How to reproduce:
1. Open the attached “TempBehaviorBug.zip” project
2. Open the “SampleScene” scene
3. Open the "Behavior Graph" asset
4. Enter Play Mode
5. In the Graph window, click the “Debug” button in the top left and select 'AGENT" from the dropdown
6. Observe the Graph window

Actual result: There is no change, making it hard to debug in playmode
Expected result: You would see changes made to the "Count" variable reflected in the UI (Like the Inspector, Animation Controller, etc.)
