So, I bought the package (when I decided to return to LII for a bit) and registered it. I went to the web site and assigned the 'gift' (white mask) to my main. It said I would have to wait for the next maintenance to occur then the mask would show up.
I'm in no hurry and so I waited. Then I noticed last night as I logged in that there was a patch. I figured, ok, this was maintenance. But when I got logged in, no mask.
