Not entirely certain if this is a bug or not, but I just had the “Your breath gives out! Your body aches.” thing happen when I had full stamina and wasn’t running. Are there other circumstances that can cause that to happen? I just went down the stairs of the evac shelter when it happened (not for the first time, either, i had done it at least once before and it didn’t happen), not sure if that’s a coincidence or not.

I think it can also happen if you’ve got a ton of mouth encumberance (ie, its hard to breath while wearing three scarves and a dust mask)
Never happened to me while I was not running but has happened a lot while running. I generally do not have much mouth encumbrance though so could be because of that.
