I am towards the end of an Empress of Cuba habano and heard a cracking sound while taking a pull on it. I looked and the wrapper leaf had split. It had been an absolute perfect smoke until that point, it had been store at 65% rh for a few months prior to smoking. Im guessing maybe the filler had been packed a bit too tightly at the point where it cracked and the heat caused it to expand thus cracking the wrapper but figured I'd ask incase I'm wrong since I've yet to experience this happen.
