Howling abyss tahm kench bug

I was playing aram and i had a few things happen, I had this funny thing were I ate someone and snowballed to someone and it worked, which should stay because it's awesome. Also, which was awesome and won us the game but should be patched, I ultied outside of the map on the parts where top and bot should be (the parts you cant go to) and it took me to their fountain. Their nexus was open so the yi i took went for it after i tanked the fountain and we won. However, it was kinda weird and probably a bug
