Hey! I'm not sure if this is where I would post this. Unfortunately, I don't have any screenshots to prove it, but I just beat the orange stake difficulty a few minutes ago using the checkered deck but the new difficulty didn't unlock and I also didn't get the new deck.
The run was not seeded and I don't use any mods. I looked on reddit and it seems like other folks may have run into the same issue (ignoring the complaints when the runs were seeded of course). Is there anything I can do? Any work arounds? Beating orange was really tough and I'm worried that if I put in the energy to beat it again, it still won't count. I have 107 hours in this game so far if that lends any credibility and this is the first time I've had this issue.
