I agree w/ sarge. Filler tobacco will absorb the extra moisture more quickly than the wrapper leaf. When this happens, the filler expands faster than the wrapper leaf (which at this point is less pliable) can handle, causing it to crack. The same thing happens when you try to re-humidify a dried out cigar too quickly.
