While using an Actor Component, Simulate Physics cannot be toggled with a Click Event if Substepping is enabled.

If Substepping is off, everything works fine. This seems to only happen if an Actor Component is driving the bp and if Click Events are toggling physics.

Steps to Reproduce

1. Download this sample project: [Link Removed]

2. Once opened, PIE
3. Click any & all of the 3 boxes to enable physics on them (note the screen printout)
4. Once they begin to move, click them again to disable physics
5. Click the boxes a thrid time to re-enable physics

Results: Physics cannot be re-enabled

Expected: For simulate physics to toggle as it does when Substepping is Off

To test without Substepping, go to > Edit > Project Settings > Engine > Physics > Framerate > disable Substepping
