The Sharandar Campaign seems to have vanished from one of my characters.
Interestingly, it is the only one of eight who has the campaign unlocked but not completed.
I bought two new slots during the sale and only recently started the characters. One just hit level 70 and had the first two Sharandar boons and just unlocked the third gate, the other has only just hit 60 and so Sharandar shows as locked. The other six have 100% completion, and all but the one who is mid way through can access the campaign through the campaign window.
On the other, it simply does not appear anywhere on the page (and I've gone through the filters...)
This happened just after the latest patch, it was definitely there on Monday, so I wonder if that has anything to do with it?
