Filigree Feather not working

[Teddy]

I'm unable to find where to report bugs, so I'm reporting here. If this is not the appropriate place, I'd appreciate if someone could point me in the right direction.

Anyway, Filigree Feather did not work for me in two games back-to-back. I'm still getting the key pieces.

On Repentance+ Key Pieces are prioritised.
Example 1: you walk into sac room, defeat Uriel and Gabriel, they will drop Key Pieces. If you pick them both up, next time you fight Angels, they will drops Angel items on defeat.
Example 2: you walk into sac room, defeat Uriel only, pick up his Key Piece and walk away. On the next floor you sacrifice again, Uriel will drop second Key Piece. If you remain in the same room and fight Gabriel, he will drop an Angel item.

same happened here, think it is a bug, would be pretty dumb to force you to fight at least 3 angels to start getting items, some runs you cant even find that many.

I fought three angels, and I still didn't get a pedestal.

It definitely seems bugged. I got the feather before running into any Angels, and the first one I fought still dropped Key Piece 1.

There's no mention of the feather in recent patch notes, and the wiki specifically calls out that Angels prioritize key piece 2 only if you already had key piece 1 before picking up the feather.

I can't imagine it's an intended change because the feather would be near worthless, as you'd need to go through 2 angels to even start getting value from it.
