(GAMEPLAY) Impossible to Devour Kalista?!

Hi everyone its the first time i report a bug A few days ago i played Tham Kench and suported a kalista who bonded with me since beggining of the game. Weird and unsual (or not), i couldnt use my W - DEvour on her. Everytime i clicked kalista nothing happened, literally. I even tried to use it on base so i didnt have the pressure of save her life in a fight and still nothing. I didnt missclick, i simply didnt devour her. Dunno if this happened before or not, but it was stressful, cause i could use my W on enmy miniuons, enemy champs e and other alliesl but not in my bot partner xD Was it because of the connection with her? OH!!!! one more thing, in the same game, another wierd thing happened. I dont know if it was bug or simply "mechanics". I usede my W on an enemy bot champ and kalista used her ulti immediatly so i could spit out or opponent in our tower, but when Kalista ultied me, my enemy came out of my mouth immediatly. Like if we couldnt combine both skills. Is it possible to do or it was jsut a bug?

PS: another bug, i played j4 yestarday, i used my ulti on enemy graves and he got out of my arena by simply walking the hell outta there. right clicking, yes... and yes, even he left a message in "all chatox#" saying it was a bug. Please check for bugs in j4's ulti :)~

Have a nice week
