A.F. Hemmingway Question

Well I am back in the Stan again, and I noticed a trend developing from last deployment; all of my hemmingway's crack as I smoke them when I am in Afghanistan. I keep the cigars in a tupador, so humidity should be fine. I think the craking is due to the extreme humidity differences from the humi to the desert. Has anyone else had this problem, and does anyone have any solutions?

Thanks,
