Shaco still has his old icon in game
In my most recent game, the enemy Shaco still had his old splash art as his icon for both the minimap and kill/assist/death announcments.
Speaking of bugs, in the same game I encountered the knock-up after death bug. You can repeat this by killing someone with a knock-up or while they are knocked up (in my case it was Janna's tornado.) Then walk away until you no longer have vision, and return to see his corpse jumping up in the air. Repeat if you have fetish for jumping corpses.
