This hack seems to solve the object_remove problems, but needs a better solution
- For some reason only the first element of the list could be deleted, so as long as you deleted in the order you made them it was ok, but any other order broke it
- This hack is bad, and I think the whole object linking thing should be moved back to a dictionary based way instead of lists
