I'm not sure if I'm the only one experiencing this, but I'm trying to buy base items from the Anniversary vendor for my leaguemates and I can't see the years on the base items. I already bought 3 wrong ones which didn't go towards any of the feats...
Yesterday I saw the same thing was going to buy base items for a feat and couldn’t find years on them.
