Unrecognized selector sent to instance, Storyboard bug after connecting a button to view controller

I was messing with my storyboard with no code involved and got this error after I connected "Terms of use" button to a view controller. It was working fine before this action.

-I created and connected a class to Terms of Use View Controller

-I used action push segue to connect

(Lame but I found the solution after I finished writing the question)

The reason for this error is I created an IBAction-UIButton method on touch up inside. I deleted that code and hoped the traces were deleted. It seems it wasnt, I had to unconnect the touch up inside by clicking the X in red squared spot.
