[Newbie] Proper class releasing

Hi All,

I'm having a problem with creating new instances of classes after other
instances of them have been released.

I have a class called BaddieManager.

In this class I have a NSMutableArray that holds instances of Baddies.

So I create a new instance, place it my array and when the Baddies life
expires, I remove it from the array. This then causes the instance to
dealloc but then the next time I call my populateBaddies function the
whole program crashes with no error message. Any help would be greatly
appreciated.

Thanks,
Jon

//populate the array with baddies
-(void) populateBaddies {

	while (baddieCount < baddieLimit) {


		//Create a new instance of my baddie
		PBaddie *newBaddie = [[PBaddie alloc] init];
		//add him to the view
		[gameView addSubview:newBaddie];
		//give him a reference of the manager
		[newBaddie attachManagerRef:self];
		//animate him
		[newBaddie animateBaddie:NULL finished:0];
		//add him to the array
		[pBaddieArray addObject:newBaddie];
		//release the temp variable
		[newBaddie release];
		//increment the count
		baddieCount = [pBaddieArray count];

	}

}

//Removes the Baddie from the array and destructs him
-(void) removeMe:(PBaddie *) pBad {

	//remove from the game view - we don't want to see it anymore
	[pBad removeFromSuperview];

	//remove the baddie from the array (Causes the Baddies dealloc
method to fire)
	[pBaddieArray removeObject:pBad];
	//update the count
	baddieCount = [pBaddieArray count];

}
