Deleting a unique_ptr
I have a unique_ptr that is stored in multiple vectors, and I don't want to manually take it out of scope by removing it from every vector.
Would deleting the object that it POINTS to take the unique_ptr out of scope?

The semantics of std::unique_ptr is sole ownership of an object.
Do not, repeat do not, create more than one std::unique_ptr pointing to the same object.
For shared ownership semantics, use std::shared_ptr
http://en.cppreference.com/w/cpp/memory/shared_ptr
In either case, let the smart pointer manage object life-time.
In an extreme case, if you are compelled to manually delete an object whose ownership is managed via smart pointers, delete it after asking the smart pointer(s) to release ownership.
