tahm kench douvour bug [gameplay]

1.ive recently bought tahm kench and the bug ive noticed when i eat a minion or champion if i double tap it fast to activate it goes on full cooldown instead of the letting me throw them while i have them in me. other times it sets me with a 6 second cooldown. this has happened to me 7 different times that ive noticed between the games ive played. 3 with minions and the rest was with a miss fortune adc. (girlfriend plays mf when i sup) im not sure if this was intended but it doesnt seem it. 2. to reproduce this just quickly click w when trying to eat minions in lane. normally i freak when saving the adc or trying to poke so i tap a button 3 to 4 times before it activates 3. sorry i dont have any screenshots or videos ive just noticed it a number of times. if it happens again i will attempt to screenshot. 4. i copy and pasted the list of how to post in this forum which is why its numbered and has a pointless number 3
