Camera handling:
* Set all new cameras as "is_active = false" automatically.
* Set loading camera as "is_active = true" upon entering loading.
* Set menu camera as "is_active = true" upon entering menu, etc.
* Maybe this has to do with loading entry/de-entry? It goes away after entering main menu...

OK new idea:
* Have one enum with all states (no split states)
* Assign a state to each camera.
* On state change, assign the camera with that state.
