ok so i know this is old and happened to me along time ago but when i got the winterized power armour which is meant to be indestructable and almost never loose any condition, it started to loose it fast than the standard metal armour, which didnt make sense. in the end i had to ditch it at my safe house in megaton and revert to using lyons pride power armour. any reason y?

It isn't indestructible! It has like a million health. It will eventually break. However I do not know why it would degrade that fast.
