Tahm Kench Bug (Can't eat ally Jinx)

So i've just lost a Rankedgame where i couldn't eat my ADC (Jinx). I tried it the whole game but it didn't work a single time. I could eat everything else (other allied, enemys and monsters). It looks like this bug was already reported sometimes and i hope it'll be fixed soon because it's really annoying. (Sorry for any grammar/spelling mistakes)
