I have a problem with ISOBEL. I dueled 2 times today, with Isobel on my side before the duels, and that's like it never happened.
Going into details I was invited to dueled twice which I accepted in the desert of Alakir, I won and lose one and the other, and it didn't validate it in the success tab.
So I cannot get the associated High Isle success.
Duelling with Isobel out is needed to finish the "mastery" of Isobel (in a few weeks for me), so it's really not "just 2 achievements", it's important.
Cheers!
