Still getting Bugsplats when trying to spectate, even though Sona isn't in the game

So I keep trying to spectate my friends' game, and I keep getting Bugsplat errors. I even messaged one and asked him if they were playing with a Sona in game (according to the alert message, Sona in-game causes this), and he said no. Just wanted to make you guys aware that it's not just Sona.

If it matters, I'm using the Mac client.

Any idea when this will be fixed? I really enjoy the spectate function...
