Spectator Mode Glitching

Champions get invisible, sometimes from start but other times when you skip back in time with the button. Turrets get placed in base when they are displayed, when someone gets killed there is no champion portrait but instead its just a blue box. Sometimes the announcer message gets glitched like instead of saying TRIPLE KILL it says display_champion_32 something like that, you know random buggy underscores and messages. This has been going on for 3 days now. I have repaired my client and tried different replays, in case either would be corrupt, but it hasn't fixed it.
