Hi,
The problem could be, that you are copying the vector directly with the
pointers .
e.g.
*) you are copying the vector -> the pointers will be copied and not the
object of your class.
*) you are deleting one of the 2 vector instances -> memory will be
freed -> everything is fine... atleast for now
*) you are deleting the 2nd vector -> the pointers are pointing to an
address that is not available anymore -> big MessageBox with errors/CRASH

That's what I thought... in that case I need to figure out why calling
delete vector[element] crashes my mod!

If the element type is a pointer:

Then the underlying object will not be destructed, just the slot holding
the ptr.
If you do:
CUtlVector< CMyClass > vecStuff;
Then the object gets desctructed (but you also have to worry about
implementing a copy constructor or operator =, etc. etc.)
Safest thing in the CUtlVector< CMyClass * > case is to loop through the
objects and call delete on each entry, and then call Purge/RemoveAll to
free the memory used for the raw pointers.
~CUtlVector will automatically clean up the ptrs, but if you don't
delete the objects in the CUtlVector< CMyClass * > case then you'll have
a leak.

Why you don't look at the code itself? In "Remove" you can see the
element
will be destroyed by the Destruct function. The Destruct function calls
the
Destructor of the element.

Am I right in assuming that if you have a vector of pointers, that
point
to
things you create with "new", you have to either call delete on each
element
or use PurgeAndDeleteElements()? Because that's what I've been using
up
until recently, where it seems that trying to delete elements from a
pointer
vector on destruction of whatever they are members of just causes the
game
to crash with a memory error. Removing the calls to delete stop the
crash,
but unless CUtlVector automatically cleans up your memory for you,
won't
this just create MASSIVE memory leaks? As far as I knew, CUtlVector
didn't
magically look after your memory for you... was I wrong?
