[GAMEPLAY] DJ Sona Bug?

So, I was just chilling and playing some Intermediate bots, enjoying my DJ Sona music. I get 947 gold and decide to B so I can start my Ardent Censer with an Aether Wisp. I buy that, and click out by my tower bot lane, casting my E so I can get out there faster, and pinging omw. I look at my minimap and see Sona still standing in spawn. Wonderful. I check other lanes for movement to see if it's just my #OhioPingLyf. It's not lag. I try selling my Aether Wisp. No dice. Cast all my skills. Nope. Try B'ing again. Successfully backed, but still stuck. I try Flashing. Sona flashes, but I still can't walk anywhere. I apologize to my teammates and DC to see if that fixes anything. I hit Reconnect and go into the loading screen. I load up surprisingly fast, but after being at 100% for 5 minutes, I still haven't got in game. Another 2 minutes elapse as I get to boards and start writing this post, before Hallelujah! I hear the Ethereal music start playing. I go back into League, and... What. The. Fuck. I'm still in the loading screen. Suddenly, the default SR music also starts playing. As of writing this sentence, I've been waiting for over 15 minutes and I'm still not in game. Reproducing this bug is as easy as 1, 2, 3... 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18.

Reproduce:

1. Go into a Summoner's Rift Intermediate bots game, with Ezreal, Jax, Cassiopeia, Garen, and Rammus on the enemy team
2. Pick Sona and switch to DJ Sona, taking Flash/Exhaust
3. Go to bot lane
4. Get to level 5, leveling your skills up in the order of Q>W>E>Q>Q, don't use either of your summoners
5. Switch to Ethereal
6. Walk into blue side bush at bot's halfway point.
7. Recall
8. Click on Ardent Censer
9. Buy Aether Wisp from the build path
10. Ping on your way to bot lane outer turret
11. Try to move
12. Recall again
13. Flash towards bot lane
14. Sell Aether Wisp
15. Leave game
16. Hit Reconnect
17. Using the 30 minutes that you're in loading screen listening to 2 songs at once, question all of your life choices
18. Go play DOTA2 or something idk

I've only had this bug once, but then again I'm still in loading screen, so...

But yeah, I'm pissed off, confused, and scared that I'm gonna get a LeaverBuster ban. It's fun. Now if you'll excuse me, I have some Super Meat Boy to get back to... Oh wait, that crashed. I have great luck with games, don't I?
