Certificate shenanigans

[torpid crater]

Just in case, here is the explanation:
The certificate created a face card, and the boss blind did not placed the card face down.

huh, looks like the debuff part of this bug was fixed, while the face-down part wasn't

peculiar

[bronze island]

this is intentional i think

cards are drawn face down, and you didn't draw that

[pearl raven]

cards added after the point where the blind ability is triggered aren't affected

[slow moss]

Same thing happens if you DNA a face card
