TAHM CANT EAT VEIGAR BUG (GAMEPLAY)

I was playing ranked as tahm and it was a normal game Top feeds mid is 0/3 ect during a mid team fight our teams veigar was caught so i flashed and W'ed to try and save him however nothing happened i stood there and we both died after the fight i told the team and veig waited in base for me to spawn i tried to eat him but nothing happened This continued for the rest of the game. IMO whenever i tried to click for example jhin tahm AI would walk to jhin to try and eat him however when i did it on veig Tahm just stood there as if i didn't even click on him. Weird bug idk
