just as beastofbodfari says in request #1993796 sometimes you can randomly get entire episode list redownloads from one or more feeds.
Please fix that if you can.
It would also help to have a stop and or a pause so you can go back and unselect the thousand or so redownloading episodes in the download list.
It is always a suprise when you have Juice set to run a check when started.
Pause would be handy at other times too.
I like Juice.
