after getting and calibrating a digital hygrometer, i believe the humidity in my humidor to be 75%. it's a new madelaine humidor and it was seasoned. this was around a week after christmas. i ordered 60 cigars from jr cigars in early january. they've been in there since then. today, 2/15/09, my brother in law and i had the first cigars from the humidor. we cut the tips of and they were crumbly. the wrapper started coming off of mine. the draw was loose at first. they burned fine and the ash was very even. i squeezed a few other cigars in the humidor and i could hear a little crackling in them.

why would this be happening when the humidity is at 75%?
