"Tab" or "o" champ display bugged

In a recent game, I was playing camille jungle. When the game started, I went to tab as normal just to look at everybody. ("o" does the same thing). I only saw one champ per side, though upon closer inspection it was that every champ was stacked on top of eachother. I did not restart, though I did try exiting client via alt+esc and re-entering which has fixed other issues along these same lines in the past. The visual bug persisted to the end of the game
