Carusel choice bugged

On my last match, at some point, we had a triple draw on first place before a carusel. We were activated at the same time and i went for a vayne with a chain vest but when we got back to our respective arenas, i had, instead, a yasuo with a rod. And i'm 100% sure i got the vayne because before going to the arena, still on the carusel, i wandered a bit with her, so is not that a picked the yasuo by mistake.
