What Is Going On?

[Old Smokey]

What was your outdoor humidity today? Something tells me in a place called Lakeway in TX might be a tad humid. If your cigar was at 73% and it is without any Rh device for a few days the wrapper would dry faster than the filler and binder. When you smoke a damp cigar that interior moisture expands as it gets hot and the dry wrapper splits. This is possibly what happened. And if you are drawing high humid air each time you puff and the filler is already on the high side Rh, there is going to be some expansion taking place.

Pretty much sums it up, I would only change "possibly what happened" to most likely what happened.
