Wintersday mini 3-pack gone?
Well, they became available on November 26th, before the Wintersday release. I guess they thought a month or so was long enough. /shrug
They were removed on midnight of New Years Day.
As for why…. I dunno. Like Inculpatus said, maybe because they just didn’t want them to be there for too long and they’d already been there over a month.
