Is there something I'm missing with the Winstance? I never get a full hour. Does it cancel under certain circumestances, like a certain number of fights. I usually use it for the last 2 fights in my league battles, then 1st 3 league battles, and however many arena battles I can do without losing my best dragons. But it just stops working before I can even do a couple of arena battles.
Attached is one screenshot. I've got many screenshots as I often want to log a fault and haven't yet. So please bear in mind that sometimes it cancels when I've got more than 30minutes to go to.
