Weird. The only way to get rid of the slime jar is to use it up, and the only way to use it up is to use it on the statue. If you reload the previous day, do you have the slime jar? If not, maybe go back a couple days, then when you have it, use it, you SHOULD get the bra. (if it somehow despawned, you will have to get the bra and play the game from there all the way to when you need to give it to the the Crimson Blade, I’m afraid)
