A bug between Nautilus and Kalista

when i played duo with my cousin, i was using nautilus and my cousin used Kalista. and for somehow, after my cousin used the bind on me, the bind is still in my cousin's item. also, the soul that kalista usually have that connect with her partner does not show on me and my cousin. Suddenly, the most weird thing happened. My cousin use the ult on me, and i couldn't used his ult . i tried to left click it, and it doesn't work. i tried to right clicked it, it didn't work as well. and the circle that usually pointed where do you want to land the ult, also DIDN'T show. moreover, there were so many lines, for somehow, came up in the circle, and it was weird. and also once, after the ult stop, i cant control my champ(nautilus) to move. it kept on following kalista wherever kalista go. so please, try to fix this bug, and apparently, we lost a ranked game because of that. Thank you.
