Super buggy Mao game - Couldn't W Cass

Now, I know that Maokai's W is supposed to tangle up their legs. And I also know that Cassiopeia doesn't have legs. But making her immune to Maokai's main engage tool is a little much...

Towards the end of the game, when everyone was collapsing, I found myself wading through a hellscape of fiddle ults and MF bullets to lock down their Cass... only to find that, no matter how I clicked on her, the root wouldn't go off. The first time I figured it was because of fiddle's silence/fear and she was just barely inside the radius, but a few moments later they re-engaged without Fiddlesticks, and I still couldn't W her, even though I was right up in her business.

Going into the game, I had a weird glitch where the game couldn't connect to server, and then, instead of going back to a reconnect screen, it went to the home screen (as though someone had dodged). I could even create a lobby, but I couldn't start a game. When I restarted the client, it jumped straight into game (again, no reconnect screen), and everything went swimmingly from there on in. (Y'know, until I tried to CC Cass, who presumably wiggled away unimpeded whilst shouting "Outplayed 360 No-Legs".)

I plan on playing Mao a bunch (especially now that there are a bunch of new non-scaling damage boost items), and would really appreciate if you could do me a solid and make sure snakes aren't literally immune to me.

Thanks, guys. Keep up the good work!
