Physics V2 Stress Test Playground: Simulation frozen for Havok

When viewing the Playground linked in the 6.0 Announcement: Physics V2 Stress Test, the simulation appears frozen for Havok. The simulation runs fine when toggled to Ammo

The PG linked in the forum was WIP.
The one from the documentation is fine.
