Unfortunately I have only now noticed that when I delete an "object", the "house" and "basement" quantities associated with that deleted object remain stored; when I go to insert a new "object" it takes the values ​​of "house" and "cellar" that have remained there from before ... how do I, when I delete an "object", also delete the quantities associated with it?
