[GAMEPLAY] Invisible Karthus on ARAM

as the title says, i came across an invisible karthus, on aram. everything was fine for the first few minutes. right around 5:00~ Karthus dies. we didnt notice before, but when he came back, he was bound to their Kalista. this may have played a part in the situation. anyway, when Karthus returned, he was invisible. the only things we could see are his particles, nametag/ health, and that he was bound to Kalista.

we had him targeted and as a main priority for a little while. as soon as the 11:11 mark hit, he was no longer invisible.

heres the match as well. http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1714984487/206259435?tab=builds&participant=7

it doesnt look like an item was purchased, which may have triggered this, since both Kalista and Karthus did not buy anything between the time Karthus was fine, and the time he bugged out. I think it may have just been an issue with the soul bind.

all members of both teams saw this, and was a first for all of us.
