[Gameplay] Jhin Ult Eaten By Tahm Kench Bug

I was recently playing as Jhin with a Tahm Kench support when I noticed a bug when I tried to use my ultimate. I opened up my ultimate and immediately afterwards, my Tahm Kench used Devour and ate me. I still saw the range indicator of my ultimate from the spot I pressed R even though I was moving around in Tahm Kench. I honestly don't know how that interaction is supposed to work but I know that what happened was not right because I was not able to shoot any of my four ultimate shots while inside of Tahm but once he spat me out, I was able to shoot again but I had no idea what the range of my ultimate was or where the shots were even going to go. I tried shooting three of my shots while trying to figure out what the pattern was for my ultimate but not a single one of my shots went towards where my mouse was. I remember at some point, I pressed R in one direction and the shot came out in the exact opposite direction of my mouse in respect of my character. In short, after I was spit out, I had no idea in which direction my shots were going go.

I know I said otherwise in the video linked below but I believe that last shot I fired, I was actually trying to shoot in the same direction the previous shot came out but when the shot was fired, it was far off to the left and not at all where my mouse was directed.
