If you move the ship along the left edge and your screen res is high enough, you'll see the turrents on your ship aiming at something not accessible.
If I delete the objects they will not be available for spawning, since C2 handles resources on a per layout basis. I've made them global so I can reuse them for (in the future) many instances.
A simple solution might be something like, on every action "if not on resource layer" or something, but it's sloppy and won't scale with what I'm trying to do well.
Edit: To reword more succinctly:
I need to be able to spawn objects, but do not want to use or keep the original that they are based from.
