Bug with Twitch & Tahm Kench

Was playing twitch with a tahm kench support when:

1. I went into Q and went invisible
2. Tahm ate me to try and save me
3. After I was spit out by Tahm I had the invisibility silhouette for the rest of the game
4. The borders of the screen did not indicate I was actually invisible
5. Was a visual glitch I was not actually invisible

Thanks!
