Thanks guys for the quick reply.
Well i do check,to make sure i am not deleting twice.

      int DeadAlive = Dragon->TestIfDead();
      MonPtr = Tail;
      if(DeadAlive == true)
      {
         if(Tail == Dragon){
            MonPtr = Dragon;
            Dragon = Dragon->Node;
            free(MonPtr);
            delete MonPtr;
         }
         else if(Dragon->Node == NULL){
            MonPtr = Dragon;
            Dragon = Tail;
            free(MonPtr);
            delete MonPtr;
         }
         else{
            for(short NDC = 0; NDC < DC; NDC++){
               MonPtr = MonPtr->Node;
               if(NDC + 1 == DC){
                  Dragon = MonPtr;
                  Dragon->Node = Dragon->Node->Node;
               }
            }
            free(MonPtr);
            delete MonPtr;
         }
      }

Here is a part of the code. THe one that is crashing...
Dragon is an object. Well,actualy its a linked list. Tail is obviously the pointer to the first Object of the linked list and MonPtr is just a ptr that is used to delete dead dragons.
So as you see i check if the monster is dead,if it is i try to delete it.
So as much as i can tell i am not deleting twice. Is there something i am missing?

Why is it that i cant delete any objects in the

while (window.isOpen())

loop?
Whenever i try to delete an object. Now matter what the object is or how it is defined the Program just crashes with an error of

_BLOCK_TYPE_IS_VALID (pHead->nBlockUse)

.
The loop might be fully empty (except the delete function) and it will crash anyways.
Thanks in advance.
