EXC_BAD_ACCESS KERN_INVALID_ADDRESS for WKWebView dealloc

Why would the below stack trace throw a EXC_BAD_ACCESS KERN_INVALID_ADDRESS because of the WKWebView? I can't tell where this is happening either.

I dont know where this is happening but here is my reference to the WKWebView in one of my nibs.

@property (strong, nonatomic) IBOutlet WKWebView *bracketWebView;
