Common beginning programmer mistake...

When doing a deletion of objects, ALWAYS delete them in
reverse order! Why? Because as they are deleted, their indexes
(indices) change (eg. when you delete object 1, then 2 becomes 1 and
3 becomes 2, etc.) Also, reverse deletion is faster, since the list
doesn't have to be shifted around after each deletion.
