Cassiopeia Miasma is invisible on Abyss

It seems that there is a bug with miasma on Howling Abyss, it is invisible, but still does the rest of its effects. This issue became apparent in this match http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1761832182/36549033?tab=overview. Hope this gets resolved soon.
