The in-game Advancements GUI says I've tamed 10/11 cat types (first screenshot.) The advancements.json file says I've tamed all but the Tuxedo type (second screenshot.) But I have tamed a Tuxedo numerous times; the third screenshot shows three tamed Tuxedos. They are definitely mine (this is singleplayer mode) and definitely tamed (they have collars and are sitting.) And unless the wiki is wrong those are Tuxedos (blank and white with green eyes.) So why has this advancement not triggered?
