Same chimney, same baro, same stove, same guy running the stove....So what changed? Different type/size/source of coal? Was the weather extremely cold and windy when you were tending the stove?
I don't disagree with Fred that a manual pipe damper might help...but if it hasn't been needed up until now, it seems like the problem lies elsewhere.
