A few of the earliest masquerade years no longer show in the shop. Were they retired?

I know in 2014 the 2011 Masquerade items retired. Are there specific years you are wondering about?

I think the older years were retired because too many items in the shop was putting strain on the servers. I think that they might be able to be un-retired this year since the shops were changed so that one tab loads at a time instead of all at once, so hopefully that will be the case.
If I can find a staff post supporting this, I'll post a link here. But I guess we'll see once Masquerade starts in a couple of weeks or so.
You'll find out when we start Masquerade if we bring back the previous years ;)
But is correct, the tabs load individually now rather than all at once so there isn't that strain that shops like the Masquerade's shops had before when all the years showed. That's why we retired different years for various holiday shops in the first place (the long loading/etc).
