Noisy capacitor LDC mics

Am I correct in thinking that large diaphragm capacitor mics are so much more liable to be noisy due to their sensitivity to the slightest dampness?
I have a AKG C414 xls mic and I suddenly had bubbling noise after I had left it on a stand with an open plastic bag as dust cover, for about two weeks. During this time the temperature had dropped 3 to 4 C and although it had been fine over the last year it was suddenly noisy. I left it on for about an hour with Phantom power on, and it was a bit better but not much. I then put it in the case with silica gel for about a week and it was then OK. None of my other mics have done this. (Ribbons, dynamics, electret capacitors etc).
The same thing happened just over a year ago when this same mic got noisy and was put away in it’s case, only to be fine about six weeks later.
I’m beginning to think it best to only have dynamics, electret capacitors, SDC’s and ribbons as they seem so much more reliable and not prone to such problems.
