Perfect analogy in laymans terms! LOLit happens...just like finding a hot girl you wanna f***k and finding out she has a VD!
I think they tend to overhumidify tubed cigars because many see it as storage device not the temporary transport device it is intended to be. i don't mind the opus tins as they don't seal very well and still allow some air movement. Again I keep my humi a little on the conservative side at 65I noticed you said tin, but I am not sure if you kept them in it in your humi. I personally never keep my cigars in the tube or tin if they come in one. I find that these are for whatever reason mold growing magnets. I don't fully take the cigars out of the tube put I keep the tube lids off and pull the cigars out a tiny bit to help air get to them. I don't know if anyone else ever notices finding mold on tubo cigars, I just seem to see it more often then cello'd or naked cigars.
