[2021] Game got ♥♥♥♥♥♥, now the Clown can't equip add-ons or offerings

When you spend bloodpoints on a character, the items/offerings/addons/perks etc that you purchase are exclusive to that character. You have to level up each character individually.

Originally posted by Ouchmaster5000: Ah, Thank you Festive Potato, that probably explains it. I guess I just didn't notice when I was playing huntress, and jumped to conclusions when the game glitched. I guess it must think I spent them on the match that never actually happened.

Have you tried buying add-ons again to see what happens? Also, even if you reinstalled, try to verify the integrity of your files through properties and see what happens.
