Tahm Kench Devour (W) bug when used on Heimerdinger's Turrets.

So I noticed a bug when I was playing against a as a . When you ate the turret, unless you spat it out immediately, the turret would pop out of your stomach after a couple of seconds, ending the Devour skill early and starting the cooldown. This one problem isn't so bad and I normally wouldn't really care about such a trivial thing, except when it comes out, it's invincible. You can still hit it and target it, but for the rest of the duration of the stopped Devour, it would not lose all of its health. It would stop at 1 and tank the hits, still firing away. Not really sure as to how to report bugs, but I felt like going ahead and throwing this up in hopes that someone would help here. I don't have any pictures or videos of it(No idea how to make that a thing), but I still wanted to throw that out there. Thanks for reading and the help!
