I'd love a "catchup" year. Between dungeons that got missed for snowglobes, dungeons/cities/facets that didn't even exist at the time, devs who weren't around at the time, etc, there's plenty of room for bells, snowglobes, and other similar old gifts with new names. It's not even unprecidented - they've already had (though long ago, admittedly) 3 different years with snowglobes. Sure, do boxes and plants with terribly low odds for rare ones if you must, but keep us happy at the same time by making it seem like you're honoring the past by helping bring those sets up to date. Same for the hourglasses; 2014 and 2015 (and 2016, and 2017, 2018, etc...)
