Strange Crash, No Debugger Clues - objective-c

Question

I am currently running this Block of code in my Level1.m file, this is the scene for the first level of my game.
#import "BankerL1.h"
#import "GameOverScene.h"
#import "BankerGameWin1.h"

#synthesize Banker = _Banker;
#synthesize WalkAction = _WalkAction;
#synthesize MoveAction = _MoveAction;

// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];
// 'layer' is an autorelease object.
BankerL1Layer *layer = [BankerL1Layer node];
// add layer as a child to scene
[scene addChild: layer];
// return the scene
return scene;

The scene starts and everything works fine except as soon as a target is added (this is what I think is happeneing) the game freezes and crashes.
I don't know if the target being added is what is causing the crash, but it seems that whenever it is time for the target to come on, it crashes.
There is nothing in the debugger that says the game crashed, Xcode things the game is still running even though it is frozen. Please help :/ thanks

Answer 1

retain the _targets array in the init method like this: _targets = [[[NSMutableArray alloc] init] retain];
