Hi,
There's a visual glitch with Yorick on Steam. His status in the Collection is still "Locked" with ????? for the name and gray chains background, after I've finally found him in the unseeded run in the Anaglyph deck (that was my last undiscovered Joker to unlock). The achievement for full discovery has popped up fine with Jokers discovered shown as 150/150, however that half-locked image appears every time I start up a game and in the Collection (see screenshot). And I'd rather see a happy Jimbo face there after all the effort, lol.
First time I've unlocked Yorick in the Challenge run where it didn't count, so it might be related. Also, I'm not the only one with this issue, there's this guy on Reddit from last year: https://www.reddit.com/r/balatro/comments/1getqop/have_i_unlocked_yorick_or_not/
P.S. Thanks for making Balatro, amazing 230 hours for me so far.
