SUMMONERS RIFT - V8.19 - Invisible Lee Sin when following a Q into a wall.
Orion / Nath on Twitter
I've seen this a few times, first at dragon and this time with the tristana. It seems as if you connect your Q at the right moment (perhaps the execute), Lee will go invisible and can't be seen until another interaction with Lee is made, using an ability for example. Being in QA myself, I would put and MOR down, but the video is pretty self explanatory xD
Hope it gets sorted soon! :)
P.s if you wanna hire me, I definitely wouldn't complain [slayer-jinx-wink]
