Ah, OK, that makes the 'mechanical' part of it the look really obvious.
I suspect you do not have a humidity gauge in the room you keep your plants in?
I get some 'rot' spots on some of my Aloes when it has been particularly humid and cool. (I would not call it cold) It is usually just a spot here and there that are ugly, but never go furhther than that because especially the last few years the periods of high humidity never last very long here.
