[Gameplay] Tham's W not working on Lux

Hi all. I'm Main Tham Kench since the champion release. And I'm tired of reporting bugs related to him. I was playing a ranked and in the middle of the teamfight I needed to eat lux to save her, but I couldn't. I tried eating her on safe situations, just to ensure that I simply couldn't do it, the W wasn't working on her. This is happening now on normal and ranked games, I think it should be fixed as soon as possible.

I included a screenshot of my skin and her skin because maybe that's related to the problem, idk. https://pbs.twimg.com/media/DT7mENQW0AEI3NO.jpg
