[Client] Item Sets Gone

Just logged in today, and my item sets were all gone. They were still there two days ago.

If they can be retrieved, I'd really appreciate it, I just got back into playing, and I was relying on those Item Sets I made a while back to help me get back into the swing of things. It's tricky enough trying to work around all the additions and changes without at least the skeleton of what I used to do.

For reference, I logged in, went to check my item sets immediately, and found them empty. Quit game, relogged in, still not there. Played match, didn't load in match, after match, still not there.
