Invisible ThunderLord Ornn??? (GAMEPLAY)

I was playing against an Ornn in norms until I noticed that he was invisible. I could only see his health bar, summoner name, any buffs that he had and his skills. If i hovered my mouse over the Ornn, I could see his champion outline. No one else on my team seemed to be experiencing the same problem as me. This has only happened to me once so far.
