I think these were the last two still missing it, all remaining uses of the global level variable are in code that doesn't get run through a level tick and are supposed to access the primary level.
The playsim really has no idea what the renderer is supposed to do here and the current system has some serious issues that eventually need addressing. So it is better to just set a flag that an actor needs to have its view interpolation reset if being used as a camera and let the render code deal with it.
This will keep the playsim clean of future changes to this feature.
