Gib set consumed without spawning Gib

Hi. I was doing a 500 lvl run and got around to spawning gib pretty late (round 283) so i used miss jilly to insta kill a random enemy. the items were consumed but miss jilly didn't change into Gib. Did i missunderstand something or is it a bug? Edit: nvm i am stupid. the card spawns in your "hand"

Yes, glad you found it!
