It has been mentioned several times in the news post on the front page, but I realised no one made an actual bug report. And since we're three weeks into this month-long event and nothing has been done about it, I figured making a report might be worth it.
Long story short: the items that were supposed to retire last year are available in this year's event shop. Both apparel and companions.
Considering retired was explained to be no longer available for outright purchase in the future (the whole reason the lootbox concept was introduced). But there's no lootbox in the shop AND it's not mentioned in the news post either. That seems inconsistent with April's Murkwood event and all information previously shared by staff.
