Miss Fortune ult blocked by Daisy [GAMEPLAY]

I will try to test to creat it again tommorow, but i might forget it overnight and would need help for that. So now to the bug,

I was playing in a ranked Game with Quinn Top, Schao Jungle, LeBlanc Mid, Miss Fortune Bot (me), Braum Support and in the enmy team Gnar Top, Vi Jungle, Veigar mid, Lucian Bot, Iwern Support. (addded link but don't know if you can see it, but hope Riot can work with it) So while a fight in the midlane Iwern casted Daisy who rushed to me and attacked me while she was directly ontop of me I ulted and my ult got blocked completly as if our Braum would have shielded it, so it might be a bug with Braum, but im not sure if he was that close. I can't give much more information though and hope that you can see the Match somehow or recreat the bug. If anyone wants to help recreat it just comment here or feel free to try for yourselfs.
