The statement that PVA gets brittle with moisture is opposite to our experience. Both temperature and moisture make PVA soft.
My experience is the same. Last night my printer jammed completely. See out of focus pic:
Had to take the whole thing apart. After cleaning out the feeder and the printcore I tried again but kept jamming. Increased tension all the way and still jammed. Then I realised how soft the filament felt and realised it must be from moisture, lots of rain and misty days lately.
Will try dry it out on a heating pad as suggested and the dry box seems like a good idea going forward. This is my first time using PVA so did not realise it was going to be this susceptible to moisture but it makes total sense.

What about UV light exposure? While I don't think that any of you is exposing the filament to sunlight there might be a difference in the light sources you use at the place where your printer stands.
