Hey there.
In one of my projects I keep the default camera in my project, however, during load-time, I search the map for key entities*, one of these key entities is a camera, if one is found, it'll delete the default camera, and use the one in the map. I don't seem to have any problems with this, and it works as expected.
If you want to simply store a location for the camera to move to (maybe a security camera, or cut-scene) I'd use a pivot, and lock the camera to that pivot
*It's useful to search the map for key entities all at one time so you can reference them later. Example: Spawn Points, HeightMap
I made a LoadMap function that wraps the Leadwerks LoadMap function to give all the extra functionality of referencing important entities, and in my case generating trees, and water.
