In live, we can use UI buttons to call FollowTarget.LateUpdate() directly to move objects and ensure execution order. In open beta, this no longer works.
This could be an il2cpp issue missing certain methods. It has been reported that AutoCam.ManualUpdate() is also missing.
Sample world:
wrld_e4785ea4-c00b-411c-80d8-7227ac7ede17
This world has a sphere and a rotating object. The sphere has a disabled follow target component and a ui button calling follow target's late update method. If the sphere is on the floor, the call failed. If the sphere is rotating, the call worked.
