Erase an object from the system.
This can also be done simultaneously with more than an object by marking the corresponding checkbox on the right and from the drop-down menu.
IMPORTANT: If we erase an object and it is currently active in some campaign, the system will warn us, preventing its elimination.
To delete it first we must remove it from the stage it is in and later try again to eliminate it.
This option will definitively delete the object for the system.
