fix for "works in editor but not in build" for Random Hoop Generator "Store Existing", "Restore Existing" functionality.
"Restore Existing" was deleting all game objects. The problem was the startup script execution order, which unity automatically organizes and can be different in the build. The specific problem was that the list of possible objects to be placed was not fully initialized before being referenced by another script. So the actual problem was the "Store Existing" function.
I repeated this startup reference in the function itself and the problem is fixed.
